What happens to the potential energy of the molecules in a reaction? A. The potential energy of the molecules changes during a reaction.
B. The reactants only lose potential energy when forming products.
C. The potential energy of the molecules does not change in a
reaction
D. The potential energy of the products is equal to that of the
reactants.

The potential energy of the molecules change during a reaction  

Explanation:

During an exothermic reaction, bonds break and new bonds form and, protons and electrons go from a structure of higher potential energy to lower potential energy. Also, energy is converted to kinetic energy, which is the heat released in reactions.

have a great day because if you dont you and i will be sad
