Question

enthalpy change and entropy change of a chemical reaction at 25°C are 177 KJ and 160.4KJ respectively. Calculate free energy change for the reaction and predict whether the reaction is spontaneous or non-spontaneous.​

Answer 1

Explanation:

Using free energy to determine spontaneity

The sign of ΔG will change from positive to negative (or vice versa) where T = ΔH/ΔS. In cases where ΔG is: negative, the process is spontaneous and may proceed in the forward direction as written.
