Question 5 The spontaneity of a reaction depends both on the enthalpy change, Delta H, and entropy change, Delta S. Reactions that release energy produce more stable products, and the universe tends toward disorder. Thus, an exothermic reaction with a positive entropy change will always be spontaneous. Mathematically, this relationship can be represented as where Delta G is the change in Gibbs free energy and T is the Kelvin temperature. If Delta G is negative, then the reaction is spontaneous....
