The variation in number of moles dni <strong>is</strong> independent of each other. However the sum of<br />
change in mole in all the ph<strong>as</strong>es must be zero. F<strong>or</strong> the criterion of equilibrium <strong>is</strong> that the<br />
chemical potential of each component must be equal in all ph<strong>as</strong>es.<br />
