Abstract

We revisit Guggenheim's theory to demonstrate that the change in Gibbs energy of athermally mixing molecules can be generalized into a model that requires only the mole fraction, volume and contact area of the various molecules. Subsequently, we obtain a general formula for the combinatorial activity coefficient for mixtures of molecules differing in size and shape.
