Question

Identify the correct statement for change of Gibbs 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

Answer 1

Correct Answer - B
If `DeltaG` system lt0,the process is spontaneous
If`DeltaG` systemgt0, the process is nonspontaneous
`DeltaG` system =0,the process is in equilibrium
