For the given reaction, sign of entropy change, nature of equilibrium mixture has to be given and also the reason for heating of reaction mixture has to be given. Concept introduction: Standard free energy change: Standard free energy change is measured by subtracting the product of temperature and standard entropy change from the standard enthalpy change of a system. ΔG o = ΔH o - TΔS o where, ΔG o - standard free energy change ΔH o - standard enthalpy change ΔS o - standard entropy change and T - temperature . Spontaneous process: The chemical or physical change can takes place by itself without the help of surroundings are called as spontaneous process.
