Considering entropy (S) as a thermodynamic parameter, the criterion for the spontaneity of any process is
(a) $\Delta S_{system} + \Delta S_{surroundings} \ \textgreater \ 0$
(b) $\Delta S_{system} - \Delta S_{surroundings} \ \textgreater \ 0$
(c) $\Delta S_{system} \ \textgreater \ 0 only$
(d) $\Delta S_{surroundings} \ \textgreater \ 0 only$

a) ΔS(system) + ΔS(surroundinga) > 0

Because From 2nd Law of Thermodynamics We Know That Entropy Of World Is Increasing!

kshubhankit16122001: The correct option is : (a) ΔSsystem + ΔSsurrounding > 0

Here the volume of gas increases from V1 to V2 at constant temperature T.
Since V1 > V2 it is obvious that the spontaneous (irreversible) isothermal expansion of a gas is accompanied by an increase in the entropy of the system and its surroundings considered together.
ΔSsystem + ΔSsurrounding > 0
