Dimension reduction method in thermodynamics of multireaction systems (I) - Mole numbers, thermodynamic properties and partial molar properties relations

When species in solution undergo multiple chemical reactions the solution m ay be treated as a solution of all species actually present or as a hypothe tical solution composed of unreacted independent species. Based on the fund amental. thermodynamic principle the relationships of the mole numbers, the molar fractions, the thermodynamic properties and the partial molar proper ties between the hypothetical solution of unreacted independent species and the equilibrated solution of actual species have been established. The hyp othetical solution provides a way of reducing the dimensionality of problem and simplifying the analysis.
