Summary

THE PAPER ILLUSTRATES HOW A PLOT OF THE EXCESS GIBBS FREE ENERGY VERSUS EXCESS ENTHALPY CAN BE USED TO ORGANIZE KNOWLEDGE OF THE NONIDEAL SOLUTION BEHAVIOUR IN BINARY LIQUID MIXTURES. SUCH A PLOT IS PARTICULARLY SUITED TO SHOW HOW TEMPERATURE CHANGES INFLUENCE THE STRENGTH AND KIND OF NONIDEAL SOLUTION BEHAVIOUR AND HOW TEMPERATURE CHANGES PROMOTE VARIOUS KINDS OF LIQUID-LIQUID IMMISCIBILITY. TO ACCOMPLISH THIS, STATISTICAL MECHANICAL PERTURBATION THEORY CALCULATIONS OF THE EXCESS FREE ENERGY AND EXCESS ENTHALPY WERE PERFORMED ON A NUMBER O LENNARD-JONES MIXTURES. THE RESULTS DEMONSTRATE HOW ENERGETIC AND ENTROPIC EFFECTS CAN EITHER COMPETE OR COOPERATE TO PRODUCE PARTICULAR KINDS OF NONIDEALITIES.
