Gibbs Free Energy - Purdue University Reactions are classified as either exothermic (H < 0) or endothermic (H > 0) on the basis of whether they give off or absorb heat. Reactions can also be classified as exergonic (G < 0) or endergonic (G > 0) on the basis of whether the free energy of the system decreases or increases during the reaction.. When a reaction is favored by both enthalpy (H o < 0) and entropy (S o > …
