The reaction energy profile can tell if a reaction is exothermic or endothermic.

Question

Quizplus · Accepted Answer

The reaction energy profile shows the difference between the potential energy of the reactants and products. If the products have lower potential energy than the reactants, then the reaction is exothermic and releases energy. If the products have higher potential energy than the reactants, then the reaction is endothermic and requires energy to be absorbed. Therefore, the reaction energy profile can be used to determine if a reaction is exothermic or endothermic.
