Identify the correct statement for change of Gibb's energy for a system `(Delta G_("system"))` at constant temeprature and pressure:

A

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

B

if `Delta G_("system") =-ve`, the process is not spontaneous

C

if `Delta G_("system")= +ve`, the process is spontaneous

D

if `Delta G_("system") =0`, the system has attained equilibrium

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaG_("system") = -ve`, the system is spontaneous process,
`Delta G_("system") = 0`, the system has attained equilibrium
`Delta G_("system") = +ve`, the system is non spontaneous.
