Chemical potential is a/an

Answer: Option D

Chemical potential acts as a driving force or potential difference to achieve chemical equilibrium like temperature acts as a driving force or potential difference for heat transfer. Higher the potential higher is the transfer.
The chemical potential when we expressed in terms of gibbs free energy it can be defined as partial molar gibbs free energy.
$$\mu ={\left(\frac{\partial nG}{\partial n_j}\right)}_{T,P,n_i}$$
Since partial molar gibbs free energy is an intensive property chemical potential is an intensive Property.
