This relation is used in the Redlich-Kister equations and Van Laar equations, as well as the Margules equations often named for one of this relation's eponyms.
An integration method named for this equation has recently been developed by David Kofke and can be used to evaluate a hard sphere fluid-solid coexistence line as a function of polydispersity. This relation is used in the Redlich-Kister equations and Van Laar equations, as well as the Margules equations often named for one of this relation's eponyms. One side of this equation has the negative entropy multiplied by change in temperature, added to volume multiplied by change in pressure. That is set equal to the summation of the number of moles of each component times the change in chemical potential for each component. Its consequence is that we cannot assign independent values to all intensive variables in a system. FTP, give ►this thermodynamics equation named for a French philosopher of science and the American namesake of a certain phase rule.
