What is chemical potential ?

Chemical potential is the change in the Gibbs free energy of a system when one mole of a substance is added at constant temperature and pressure.

                    μ=(∂G/∂n)ₜ,ₚ

where G is Gibbs free energy and n is the number of moles.

● Chemical potential represents the driving.     force for the movement of particles.

☆ Particles naturally move from higher.             chemical potential to lower chemical potential.

☆ At equilibrium, the chemical potential is.       the  same throughout the system.
