Answer: It shows whether the reaction is exothermic or endothermic.

Explanation:

  • If the potential energy of the products is greater than that of the reactants, then the reaction is exothermic.
  • If the potential energy of the reactants is greater than that of the products, then the reaction is endothermic.
