Gibbs free energy at constant pressure and temperature under equilibrium conditions is

A. ∞

B. 0

C. Maximum

D. Minimum

Answer: Option D

Solution(By Examveda Team)

The gibbs free energy change as given by second law of thermodynamics goes on decreasing for an spontaneous irreversible process of constant temperature and pressure and finally when it is reached equilibrium the change is zero. Hence we can say a minimum exists for gibbs free energy.
