Question

How does the potential energy of the reactants compare to the potential energy of the products in an exothermic reaction, and where does the energy that is given off come from?

Answer 1

Q1: The reactants’ potential energies are greater than the products’ potential energies. Q2: The reactants’ potential energies are less than the products’ potential energies.
