Various ways of building quasi-Newton matrix approximations that satisfy the special form of the Gibbs-Duhem equation are studied. Partition symmetry, the separability of the functions In y and In 4, and the method of iterated projections are used in order t o develop thermodynamically consistent ma

The exact forms of the Gibbs-Duhem equation in terms of fugacities and activity coefficients, applicable to any multicomponent phase, are developed in a straightforward manner. Reduction to restricted equations valid for constant temperature, constant pressure, or constant composition becomes a simp
Duhem equation at isobaric conditions, is derived in order to replace the derivative equivalent terms of easy calculation. The E term is then evaluated for some mixtures with strong departures from ideality to obtain an order of magnitude and trend of E vs. composition: the correction, depending on
