<P> An exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy), indicating a spontaneous reaction . For processes that take place under constant pressure and temperature conditions, the Gibbs free energy is used whereas the Helmholtz energy is used for processes that take place under constant volume and temperature conditions . </P> <P> Symbolically, the release of free energy, G, in an exergonic reaction (at constant pressure and temperature) is denoted as </P> <Dl> <Dd> Δ G = G p r o d u c t s − G r e a c t a n t s <0 . (\ displaystyle \ Delta G = G_ (\ rm (products)) - G_ (\ rm (reactants)) <0. \,) </Dd> </Dl> <Dd> Δ G = G p r o d u c t s − G r e a c t a n t s <0 . (\ displaystyle \ Delta G = G_ (\ rm (products)) - G_ (\ rm (reactants)) <0. \,) </Dd>
