If the final potential energy is higher than the initial it means that energy was gained by the product, meaning that it is an endothermic reaction.
If the final potential energy is lower than the initial it means that energy was lost to form the product, and it is exothermic.

Explanation:

Law of conservation of energy
If potential energy changes that difference in energy is either absorbed by the molecule or released.
