Partial molar free energy of an element A in solution is same as its

A. Chemical potential

B. Activity

C. Fugacity

D. Activity co-efficient

Answer: Option A

Solution(By Examveda Team)

The chemical potential is nothing but the partial molar Gibbs free energy.
$${\mu _i} = \left( {\frac{{\partial nG}}{{\partial {n_i}}}} \right)d{n_i}$$
By which we can tell whether the chemical equilibrium is reached by a system or not.
