Abstract
Due to the recent availability of accurate measurements, the use of partial molar quantities (free energy, enthalpy, and entropy) has emerged as a tool aimed at evaluating effective pair interactions in nonstoichiometric compounds. In the present paper, this approach has been used to ascertain the validity of inverse methods in a simple academic case and to discuss available thermodynamic data in the most extensively studied system, i.e., , in the framework of asymmetric two-dimensional lattice-gas models proposed for this system.
