Abstract
Excess Gibbs energy change of subregular-type binary solution can be approximated with an insignifi cant error by the equation: where xi – mole fractions of components in a solution; Q0 ‒ mixing energy; m and n – numeric constants. Fixed parameters Q0 , m and n were determined by the least square method using experimental values of ΔG E and component activities of a binary solution. The obtained calculated expressions allow working with subregular solutions the same way as with regular solutions and getting simpler expressions of component activities in a multicomponent solution
