Considering entropy `(S)` as a theromodynamic parameter, the criterion for the spontaneity of any process is

A

`Delta S_("surroundings") gt 0`only

B

`Delta S_("system") + Delta S_("surroundings") gt 0`

C

`Delta_("system") + Delta S_("surrounding") lt 0`

D

`Delta S_("system") gt 0` only

Text Solution

Verified by Experts

The correct Answer is:
B
The connectivity between entropy and the spontane ity of a reaction is expressed by the second law of thermodynamics:
The entropy of the univere (system + surrounding) increases in a spontaneous process and remains unchanged in an equilibrium process.
