The effect of liquid expansion on the athermal entropy of a mixture has generally been recognized but almost disregarded in interpreting solution behavior. The principal reason for this neglect has been due to a lack of a satisfactory equation for predicting the effect. Thus, by ignoring this effect, solution theories have developed where the properties of a liquid mixture are considered to be the result of the following two effects [1]: (1) molecular size effects such as predicted by the Flory-Huggins entropy equation [2,3]; and (2) group interaction effects calculated from measured property data after subtracting effects due to size[1].
