We’re being asked to classify each given reaction as exothermic or endothermic.
• Exothermic reactions: lose energy and involve bonds forming; ΔH is negative
• Endothermic reactions: gain energy and involve bonds breaking; ΔH is positive
Predict whether the following reactions will be exothermic or endothermic.
a. N2(g) + 3H2(g) → 2NH3
b. S(g) + O2(g) → SO2(g)
c. 2H2O(g) → 2H2(g) + O2(g)
d. 2F(g) → F2(g)
