Reaction Spontaneity worksheet with fill-in-the-blank questions and a prediction task on entropy change.
Worksheet titled "Reaction Spontaneity" with two activities. Activity 1 asks to complete statements using terms like "spontaneous process," "entropy," "free energy," and "second law of thermodynamics." Activity 2 asks to predict entropy change for the reaction N₂(g) + 3H₂(g) → 2NH₃(g) and explain reasoning.
