| Abstract: | A strategy is described for the systematic generation of a complete set of partial derivatives of the four energy functions from a basis set of five measured properties: Vm, Sm, Cp,m (δVm/δT)p and either (δVm/δp)T or (δVm/δp)s. The same set of equations applies to both pure substances and either real or ideal mixtures. Examples are given of some excess differential properties of binary mixtures which exhibit unusual sensitivity to changes in composition. |
