Gibbs duhem equation

Web• This expression is called the Gibbs-Duhem equation. At constant T and P and for a binary solution the Gibbs-Duhem equation has the form B AB A n dd n µ=− µ (18.8) • The equation 18.8 means a change in chemical potential of component B is related to a change in the chemical potential of component A by a simple ratio of the moles present.
