Question

prove that change in gibbs free energy change should be negative for spontaneity

Answer 1

Answer:

When the reaction is exothermic, enthalpy of the system is negative making Gibbs free energy negative. Hence, we can say that all exothermic reactions are spontaneous. ... Temperature is very high to make the Gibbs energy value negative. Entropy change is very high to make the Gibbs free energy negative.
