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....

Suppose the Gibbs free energy change of a reaction has a large positive value. What does this say about the spontaneity of the chemical reaction? Select the correct answer below: O The chemical reaction is spontaneous. O The chemical reaction is not spontaneous. O The Gibbs free energy change, in itself, says nothing about whether a reaction is spontaneous O There is not enough information provided for a definitive answer
