For a spontaneous process in an isolated system,the change in entropy is positive.

Vedclass · Answer

(A) For any spontaneous process in an isolated system,the total entropy of the system must increase,i.e.,$\Delta S_{total} > 0$. This is a fundamental criterion derived from the second law of thermodynamics. Option $A$ is correct because it states that the entropy change is positive for a spontaneous process in an isolated system. Options $B$ and $C$ are incorrect because spontaneity depends on both enthalpy and entropy $(\Delta G = \Delta H - T\Delta S)$. Option $D$ is incorrect because both enthalpy and entropy changes determine spontaneity.
