Answer:
The total chemical potencial energy of the reactants is greater than the total chemical potencial energy of the products. (second option)
Step-by-step explanation:
An exothermic reaction is characterized by the release of energy.
This energy released is due to the fact that the products end up with less potential energy than the reactants. So, the total chemical potencial energy of the reactants is greater than the total chemical potencial energy of the products.
We can see this effect in the following graph:
