Question

Considering entropy `(S)` as a thermodynamics parameter, the criterion for the spontaneity of any process is
A. `DeltaS_("system")+DeltaS_("surrounding")be+ve`
B. `DeltaS_("system")-DeltaS_("surroundings")be`+ve
C. `DeltaS_("system")`be zero
D. `DeltaS_("surroundings")be` zero

Answer 1

Correct Answer - C
For a spontaneous process,
`DeltaS_("total")=DeltaS_(system)Delta_("surrounding")` be positive.
