Based on the theory of radial distribution function, a new unified model for excess enthalpy and excess Gibbs free energy of liquid solution was proposed.

The calculation method of Gibbs energy change of the chemical reaction in metallurgical solution has been revealed in detail, and the dimensions involved in the revealation have been strictly defined.
