What happens to the potential energy of the molecules in a reaction?
A. The reactants only lose potential energy when forming products.
B. The potential energy of the products is equal to that of the reactants.
C. The potential energy of the molecules does not change in a reaction.
D. The potential energy of the molecules changes during a reaction.
Answer (1)
The potential energy of molecules changes during a chemical reaction, either decreasing or increasing depending on the type of reaction. In exothermic reactions, energy is released, while in endothermic reactions, energy is absorbed. Thus, option D is correct. ;
