Vedclass · Accepted Answer

For an irreversible spontaneous process,the entropy of an isolated system increases.

Vedclass · Answer

(B) According to the $2^{nd}$ Law of Thermodynamics,for any spontaneous process in an isolated system,the total entropy change $(\Delta S_{total})$ must be greater than zero,i.e.,$\Delta S_{total} > 0$.For an irreversible spontaneous process,the entropy of the universe (system   surroundings) increases.Specifically,for an isolated system,$\Delta S_{system} > 0$ for an irreversible spontaneous process.Option $B$ correctly states that for an irreversible spontaneous process,the entropy of an isolated system increases.
