A) \[\Delta \,{{S}_{\text{system}}}+\Delta {{S}_{\text{surroundings}}}>0\]
B) \[\Delta \,{{S}_{\text{system}}}-\Delta {{S}_{\text{surroundings}}}>0\]
C) \[\Delta \,{{S}_{\text{system}}}>0\] only
D) \[\Delta {{S}_{\text{surroundings}}}>0\] only
Correct Answer: A
Solution :
For spontaneous process, must be positive. In reversible process |
Hence, system is present in equilibrium. |
(i.e., it is not spontaneous process) |
While in irreversible process |
Hence, in the process is positive. |
