Chemical Equilibrium Worksheet Worksheet for 11th - 12th Grade ... - Free Printable

Let’s solve this step by step.

We are given a table with 10 items (a to j), each showing changes in:
- Autonomous Spending (ΔA)
- Investment (ΔI)
- Government Spending (ΔG)
- Taxes (ΔT)
- Net Exports (ΔNX)

And we’re told:
> “Complete the following chart by writing left, right or none for equilibrium shift, and decreases, increases or remains the same for the value of r.”

Also note:
MPC = 0.8 → so MPS = 1 - 0.8 = 0.2
→ So the spending multiplier is 1 / MPS = 1 / 0.2 = 5

But wait — taxes also affect aggregate demand, but through the tax multiplier:
Tax multiplier = -MPC / MPS = -0.8 / 0.2 = -4

Net exports work like autonomous spending — they directly shift AD.

---

Step-by-step for each row:

We need to find:
1. Equilibrium Shift: Left, Right, or None?
→ Depends on whether total change in Aggregate Demand (AD) is negative, positive, or zero.

2. Value of r (interest rate): Increases, Decreases, or Remains the Same?
→ This depends on how the central bank responds OR if we assume money market adjusts via IS-LM. But since no monetary policy is mentioned, we assume standard Keynesian cross + loanable funds or simple AD-AS with interest rate adjusting to clear money market.

Actually — looking at the context (“equilibrium shift” and “value of r”), this is likely using the IS-LM model or at least assuming that when AD shifts, output changes, which affects money demand, which affects interest rates — unless the central bank offsets it.

BUT — the problem says: “for equilibrium shift” — meaning goods market equilibrium (Y). And then “value of r” — probably real interest rate in loanable funds or LM curve.

However, in many intro macro courses, when you have fiscal/external shocks, and no mention of monetary policy response, we assume:

- If AD increases → Y increases → money demand increases → r increases (if money supply fixed).
- If AD decreases → Y decreases → money demand decreases → r decreases.

So we’ll use that logic.

Also, note: The problem says “does not affect equilibrium net exports” — that’s just telling us ΔNX is exogenous, not affected by income here.

---

Let’s go row by row.

---

#### Row a:
ΔA = right → wait, no — look again.

The columns are:
- Autonomous Spend. → has "right" written? That can’t be — probably misread.

Wait — looking back at the image description (even though I shouldn't describe it), the user pasted text:

In the first table:

Row a:
Autonomous Spend.: right ← that must be a mistake. Probably it's meant to be numerical? Or perhaps "right" is under Equilibrium Shift? No.

Wait — let me re-read the user input.

User wrote:

```
a. Autonomous Spend.: right Inv.: Govt.: Taxes: Net Exp.:
Equilibrium Shift: Value of r:
```

This seems messy. Actually, looking carefully — in the original image (which I can’t see but from your paste), it appears that for row a, under “Autonomous Spend.” it says “right”, but that doesn’t make sense — because autonomous spend should be a number or direction of change.

Wait — perhaps there was a formatting error. Let me interpret based on standard problems.

Actually, rereading your initial prompt:

You said: “Complete the following chart by writing left, right or none for equilibrium shift, and decreases, increases or remains the same for the value of r.”

And the table has columns:

For each item (a-j):

- Autonomous Spend. [change]
- Inv. [change]
- Govt. [change]
- Taxes [change]
- Net Exp. [change]

Then below those, two rows per item:

- Equilibrium Shift: _____
- Value of r: _______

But in your text paste, for row a, it shows:

“a. Autonomous Spend.: right” — that must be an error. Probably “right” is meant to be under “Equilibrium Shift”? But no — the instruction is to fill in Equilibrium Shift and Value of r.

Wait — perhaps in the image, some cells already have values filled? For example, maybe for row a, Autonomous Spend. changed by +$100 billion or something, and “right” is written elsewhere?

This is confusing.

Alternative approach: Look at row b — it says:

b. Autonomous Spend.: $100 bil → ah! Here it is.

In your text:

After row a, you have:

b. Autonomous Spend.: $100 bil → so probably row a had a different value.

Wait — let me reconstruct from your paste:

You wrote:

```
a. Autonomous Spend.: right Inv.: Govt.: Taxes: Net Exp.:
Equilibrium Shift: Value of r:

b. Autonomous Spend.: $100 bil Inv.: Govt.: Taxes: Net Exp.:
Equilibrium Shift: Value of r:
```

That suggests that for row a, “Autonomous Spend.” column has the word “right” — which is odd. Perhaps it’s a typo, and it’s supposed to be a number? Or maybe “right” indicates direction?

Another possibility: In some tables, they write “increase” or “decrease” as words, but here for row b it’s “$100 bil”, so likely numbers.

Perhaps for row a, it’s “+$100 bil” but got miswritten as “right”? Unlikely.

Wait — look at row c: “Autonomous Spend.: -$50 bil”

Row d: “Inv.: +$75 bil”

So probably, for row a, “Autonomous Spend.: right” is a mistake — and it should be a number. But what number?

Alternatively — maybe “right” is indicating the direction of change for autonomous spending? Like “increases” = rightward shift? But that would be redundant.

I think there’s a formatting issue in your paste.

Let me try to infer from common textbook problems.

Often, such tables have:

Item | ΔA | ΔI | ΔG | ΔT | ΔNX | Equil Shift | r

And for row a, perhaps ΔA = +$100 billion? But row b is +$100 billion.

Wait — in your paste, after row a, you have:

“b. Autonomous Spend.: $100 bil”

Then later:

“c. Autonomous Spend.: -$50 bil”

“d. Inv.: +$75 bil”

“e. Govt.: +$60 bil”

“f. Taxes: -$40 bil”

“g. Net Exp.: +$30 bil”

“h. Autonomous Spend.: +$200 bil; Taxes: +$100 bil”

“i. Inv.: -$50 bil; Govt.: +$50 bil”

“j. Govt.: +$100 bil; Taxes: +$100 bil”

Ah! Now I see — for rows h, i, j, multiple changes are listed.

So for row a, only “Autonomous Spend.: right” — that must be an error. Perhaps it’s “+$100 bil” but typed as “right”? Or maybe it’s “no change”?

Another idea: In some versions, “right” might mean “increases”, but that’s unusual.

Perhaps “right” is under “Equilibrium Shift” for row a? But in your paste, it’s under “Autonomous Spend.”.

Let’s look at the very beginning of your message:

“You uploaded an image containing a task.”

And then you pasted text that includes:

```
a. Autonomous Spend.: right Inv.: Govt.: Taxes: Net Exp.:
Equilibrium Shift: Value of r:
```

This suggests that in the image, for row a, the cell under “Autonomous Spend.” contains the word “right”, which is probably a mistake — or perhaps it’s indicating that autonomous spending increased, causing a rightward shift, but that’s circular.

I think the most reasonable assumption is that for row a, “Autonomous Spend.” changed by +$100 billion, same as row b, but that doesn’t make sense.

Wait — perhaps “right” is a placeholder, and we are to assume no change? But then why write “right”?

Another thought: In some contexts, “right” might mean “positive change”, but it’s ambiguous.

Let’s skip row a for now and do the others, then come back.

Perhaps from the pattern, row a is meant to be a baseline or something.

Let’s list all rows with their changes as best as we can interpret:

From your paste:

- a. Autonomous Spend.: right → ??? Let's assume this is a typo and it's +$100 bil, but row b is also +$100 bil. Or perhaps it's 0? But then "right" doesn't fit.

Wait — look at the second part of your paste:

After the first table, you have:

"Assume MPC = 0.8, T = $100 bil, s = 0.2 (and demonstrate that pure savings and net exports do not affect equilibrium net exports)"

Then another table with items 1 to 10, but that seems separate.

Actually, rereading your entire input, it seems there are two parts:

First part: Table with a to j, asking for equilibrium shift and r.

Second part: Another table with 1 to 10, but that might be for a different question.

In your initial request, you said: "Solve the problem accurately." and referred to the image.

Given the confusion, I'll focus on the first table (a to j) and assume that for row a, "Autonomous Spend.: right" is meant to be "+$100 billion" or something similar. But to resolve this, let's look for clues.

Notice that in row b, it's "Autonomous Spend.: $100 bil" — likely +$100 bil.

Row c: "-$50 bil"

Row d: "Inv.: +$75 bil" — so investment increases by $75 bil

Row e: "Govt.: +$60 bil"

Row f: "Taxes: -$40 bil" — tax cut

Row g: "Net Exp.: +$30 bil"

Row h: "Autonomous Spend.: +$200 bil; Taxes: +$100 bil" — so both increase

Row i: "Inv.: -$50 bil; Govt.: +$50 bil"

Row j: "Govt.: +$100 bil; Taxes: +$100 bil"

For row a, since it's listed first, and "right" is written, perhaps it's a trick — "right" means no change? Or perhaps it's +$0.

Another idea: In some tables, "right" might indicate the direction of the shift, but that's what we're supposed to fill in.

I think the safest assumption is that for row a, there is no change in any component — so all deltas are 0. Then equilibrium shift is "none", and r "remains the same".

But why write "right" under Autonomous Spend.?

Perhaps "right" is a misplacement, and it's meant to be under "Equilibrium Shift" for a different row.

Let's count the rows.

In your paste, after "a.", you have "b.", etc., up to "j.".

For row a, only "Autonomous Spend.: right" is specified, others blank.

Perhaps "right" means that autonomous spending increased, and we are to take it as +X, but X is not given. That can't be.

Unless "right" is a code for +$100 billion, as in row b.

I recall that in some textbooks, they use "right" to mean "increases", but it's rare.

Perhaps it's a typo, and it's " +$100 bil ".

To move forward, I'll assume that for row a, Autonomous Spending increases by $100 billion, same as row b. But that would make a and b identical, which is unlikely.

Another possibility: "right" means that the AD curve shifts right, but that's the answer, not the input.

I think there's a formatting error in your paste. Given that, and to provide a solution, I'll assume that for row a, there is no change in any variable — so all deltas are 0. Then:

- Equilibrium Shift: none
- Value of r: remains the same

For other rows, we can calculate.

Let's define the effect on Aggregate Demand (AD).

AD = C + I + G + NX

C = C0 + MPC*(Y - T) , but for changes, the change in AD due to changes in components is:

ΔAD = ΔA + ΔI + ΔG + ΔNX + (tax multiplier)*ΔT

Where tax multiplier = -MPC/MPS = -0.8/0.2 = -4

Spending multiplier for A,I,G,NX is 5.

So for any change, the total change in equilibrium Y is:

ΔY = multiplier * (ΔA + ΔI + ΔG + ΔNX) + tax_multiplier * ΔT

= 5*(ΔA + ΔI + ΔG + ΔNX) + (-4)*ΔT

Then, if ΔY > 0, equilibrium shifts right; if <0, left; if=0, none.

For interest rate r: if Y increases, money demand increases, so if money supply is fixed, r increases. If Y decreases, r decreases. If Y unchanged, r unchanged.

We'll assume that.

Now let's do each row.

First, row a: Assume no changes. So ΔA=0, ΔI=0, ΔG=0, ΔT=0, ΔNX=0

ΔY = 5*(0) + (-4)*0 = 0 → equilibrium shift: none

r: remains the same

But this is guesswork.

Perhaps "right" means +$100 billion for autonomous spending. Let's try that.

Assume for row a: ΔA = +100, others 0

Then ΔY = 5*100 + (-4)*0 = 500 >0 → shift right

r: increases (since Y increases)

Similarly for row b: same thing.

But then a and b are the same.

Unless for row a, "right" is under a different column.

Let's look at your paste again:

"a. Autonomous Spend.: right Inv.: Govt.: Taxes: Net Exp.:
Equilibrium Shift: Value of r: "

Perhaps "right" is the value for "Equilibrium Shift" for row a, but that doesn't make sense because we're to fill it in.

I think the only logical way is to assume that for row a, there is a change in autonomous spending of +$100 billion, as it's the first item, and "right" is a misnomer for "increase".

Or perhaps "right" means the shift is to the right, but that's the answer.

I found a better approach: in some online sources, similar problems have row a as "Autonomous spending increases by $100 billion", so I'll assume that.

So for row a: ΔA = +100, others 0

ΔY = 5*100 = 500 >0 → shift right

r: increases

Row b: same as a? But in your paste, row b is "Autonomous Spend.: $100 bil" — likely +100, so same as a.

That can't be. Unless row a is different.

Perhaps for row a, "right" means no change, and "right" is a label.

I give up on row a for now. Let's do row b to j, and for row a, I'll put "none" and "remains the same" as a default.

But let's calculate all.

Define:

Multiplier for spending (A,I,G,NX): k = 1/(1-MPC) = 1/0.2 = 5

Tax multiplier: k_t = -MPC/(1-MPC) = -0.8/0.2 = -4

So ΔY = 5*(ΔA + ΔI + ΔG + ΔNX) + (-4)*ΔT

Then:

- If ΔY > 0, equilibrium shift: right
- If ΔY < 0, left
- If ΔY = 0, none

For r:
- If ΔY > 0, r increases (assuming money supply constant)
- If ΔY < 0, r decreases
- If ΔY = 0, r remains the same

Now let's do each row.

Row a: Assume ΔA = +100 (interpreting "right" as +100 billion), others 0

ΔY = 5*100 + (-4)*0 = 500 >0 → shift right

r: increases

Row b: ΔA = +100, others 0 → same as a: shift right, r increases

But that's duplicate. Perhaps row a is 0.

Another idea: in the image, for row a, "Autonomous Spend." might have "0" or "no change", and "right" is under "Equilibrium Shift" for a different reason.

Perhaps "right" is a mistake, and it's " +$0 ".

I think for the sake of progress, I'll assume that for row a, there is no change, so:

a. ΔY = 0 → shift none, r remains same

b. ΔA = +100 → ΔY = 5*100 = 500 >0 → shift right, r increases

c. ΔA = -50 → ΔY = 5*(-50) = -250 <0 → shift left, r decreases

d. ΔI = +75 → ΔY = 5*75 = 375 >0 → shift right, r increases

e. ΔG = +60 → ΔY = 5*60 = 300 >0 → shift right, r increases

f. ΔT = -40 → tax cut, so ΔY = (-4)*(-40) = +160 >0 → shift right, r increases

g. ΔNX = +30 → ΔY = 5*30 = 150 >0 → shift right, r increases

h. ΔA = +200, ΔT = +100

ΔY = 5*200 + (-4)*100 = 1000 - 400 = 600 >0 → shift right, r increases

i. ΔI = -50, ΔG = +50

ΔY = 5*(-50 + 50) + (-4)*0 = 5*0 = 0 → shift none, r remains same

j. ΔG = +100, ΔT = +100

ΔY = 5*100 + (-4)*100 = 500 - 400 = 100 >0 → shift right, r increases

Now for row a, if we assume no change, then:

a. shift none, r remains same

But in your paste, it has "right" under Autonomous Spend., which might imply a change.

Perhaps "right" means that autonomous spending increased, and we are to take it as +100, but then b is also +100.

Unless row b is different.

Another possibility: in row a, "right" is under "Inv." or another column, but in your paste, it's under "Autonomous Spend.".

I think the best course is to proceed with the calculations as above, and for row a, since it's ambiguous, I'll put "none" and "remains the same", assuming no change.

So summary:

a. Equilibrium Shift: none, Value of r: remains the same

b. right, increases

c. left, decreases

d. right, increases

e. right, increases

f. right, increases

g. right, increases

h. right, increases

i. none, remains the same

j. right, increases

But for row f: ΔT = -40, so tax cut, which increases disposable income, so consumption increases, so AD increases, so Y increases, r increases — yes.

For row i: ΔI = -50, ΔG = +50, so net change in spending is 0, so ΔY = 0, so no shift, r unchanged.

For row j: ΔG = +100, ΔT = +100, so government spending increases by 100, taxes increase by 100, so the balanced budget multiplier is 1, so ΔY = 1*100 = 100 >0, so shift right, r increases — matches our calculation: 5*100 + (-4)*100 = 500-400=100.

Good.

Now for row a, if we must have a change, perhaps "right" means +100, but then it's same as b.

Perhaps in the image, row a has "Autonomous Spend.: +$100 bil" and "right" is a distractor.

I think for consistency, I'll keep a as no change.

So final answers:

a. none, remains the same

b. right, increases

c. left, decreases

d. right, increases

e. right, increases

f. right, increases

g. right, increases

h. right, increases

i. none, remains the same

j. right, increases

But let's double-check row f: ΔT = -40, so tax decrease, which is expansionary, so AD increases, Y increases, r increases — correct.

Row c: ΔA = -50, contractionary, Y decreases, r decreases — correct.

Row i: offsetting changes, no net effect — correct.

Row j: balanced budget, but since MPC<1, the multiplier is less than 1 for taxes, but in this case, with MPC=0.8, balanced budget multiplier is 1, so ΔY = ΔG = 100, so yes, shift right.

All good.

For row a, I'll stick with no change.

So the completed chart is:

a. Equilibrium Shift: none, Value of r: remains the same

b. right, increases

c. left, decreases

d. right, increases

e. right, increases

f. right, increases

g. right, increases

h. right, increases

i. none, remains the same

j. right, increases

Now, to present in the format.

Final Answer:

a. Equilibrium Shift: none, Value of r: remains the same
b. Equilibrium Shift: right, Value of r: increases
c. Equilibrium Shift: left, Value of r: decreases
d. Equilibrium Shift: right, Value of r: increases
e. Equilibrium Shift: right, Value of r: increases
f. Equilibrium Shift: right, Value of r: increases
g. Equilibrium Shift: right, Value of r: increases
h. Equilibrium Shift: right, Value of r: increases
i. Equilibrium Shift: none, Value of r: remains the same
j. Equilibrium Shift: right, Value of r: increases
