. Identify the correct statement for change of Gibbs energy for a system


(ΔGsystem) at constant temperature and pressure.

(a) If ΔG < 0, the process is not spontaneous.

(b) If ΔGsystem > 0, the process is spontaneous.

(c) ΔGsystem =0, the system has attained equilibrium.

(d) If ΔGsystem= 0, the system is still moving in a particular direction.

 

Best Answer

Correct Option is:  (c )

reaction is spontaneous when- ΔG is negative

ALSO - non spontaneous when ΔG is positive 

at equilibrium when ΔG = 0
