WebAdd a comment. -1. The change in enthalpy is negative in an exothermic reaction because energy is "lost" through the reaction (because there is more energy on the products side than on the reactants side). Another way to think about this is by calculating the enthalpy before and after a reaction, for example - and this is a synthesis [and ... WebAug 13, 2024 · Spontaneous reactions release free energy as they proceed. Recall that the determining factors for spontaneity of a reaction are the enthalpy and entropy changes that occur for the system.
