Identify the correct statement for change of Gibbs free energy for a system `(DeltaG_("system"))` at constant temperature and pressure.

A

) If `DeltaG_(system)` gt 0, the process is spontaneous

B

If `DeltaG_(system)` = 0, the system has attained equilibrium

C

If `DeltaG_(system)` = 0, the system is still moving in a particular direction

D

If `DeltaG_(system)` lt 0, the process is not spontaneous

Text Solution

Verified by Experts

The correct Answer is:
B
If `DeltaG` system lt0,the process is spontaneous
If`DeltaG` systemgt0, the process is nonspontaneous
`DeltaG` system =0,the process is in equilibrium
