- In an endothermic reaction, the products have higher stored chemical energy than the reactants, meaning energy is absorbed from the surroundings during the reaction.
- In an exothermic reaction, the products have lower stored chemical energy than the reactants, meaning energy is released to the surroundings during the reaction.
- The direction of the reaction is shown along the horizontal axis, while the vertical axis represents the stored chemical energy of the substances involved.
- The difference in energy levels between reactants and products determines whether a reaction is endothermic (energy absorbed) or exothermic (energy released).
Parent Tip: Review the logic above to help your child master the concept of endothermic and exothermic worksheet.
