The sign of ΔS o and spontaneity of the given reaction has to be determined. 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.
