Le Châtelier's principle: the effect of temperature on the solubility of solids in liquidsBrice, L. K. The purpose of this article is to provide a rigorous but straightforward thermodynamic treatment of the temperature dependence of solubility of solids in liquids that is suitable for presentation at the undergraduate level. The present discussion may suggest how to approach the qualitative aspects of the subject for freshman. Brice, L. K. J. Chem. Educ.1983, 60, 387.

JavaScript Programs To Calculate Thermodynamic Properties Using Cubic Equations of StatePatrick J. Barrie Cubic equations of state are widely used by chemists and chemical engineers to predict the thermodynamic properties of both pure substances and mixtures. In particular, these equations enable predictions concerning the temperature and pressure at which vapor liquid equilibrium occurs. These two educational JavaScript programs perform calculations using cubic equations of state and, equally importantly, explain how the calculations are performed.
