In the reaction A → B + C + heat
A) there is a net input of energy.

C) the potential energy of the products is less than that of the reactant.
D) entropy has decreased.

Question

Quizplus · Accepted Answer

The reaction releases heat, indicating a decrease in potential energy. Therefore, the potential energy of the products (B and C) is less than that of the reactant (A). This process is exothermic, and there is no net input of energy. The entropy may or may not have changed, but it is not related to the potential energy.
