Vedclass · Answer

(C) The criterion for the spontaneity of any process in terms of entropy is based on the Second Law of Thermodynamics. For a process to be spontaneous,the total entropy change of the universe must be positive. $\Delta S_{total} = \Delta S_{system} + \Delta S_{surroundings} > 0$. This indicates that the entropy of the system and its surroundings considered together must increase for an irreversible (spontaneous) process.
