Criteria For Spontaneity In Terms Of H, S and G – TyroCity

1. Exothermic reaction with increase in entropy For exothermic reaction, ΔH = -ve For increase in entropy, ΔS = +ve For such process, the sign of G is always negative. So such process are spontaneous at all temperature. 2. Exothermic reaction with decrease in entropy For exothermic reaction, ΔH = -ve For decrease in entropy, ΔS = -ve
