Abstract : A review of certain lattice theories is presented for deriving Flory's formula for the free energy of a solution consisting of monomer and polymer molecules. The results are then reformulated, making them applicable to simple liquids reqarded as a binary mixture of highly symmetric molecules and fractionalsized holes. These results are adapted to provide a theory of gas adsorption in which the fractional hole size concept is utilized. One obtains isotherm equations and expressions for the partial molecular configurational entropies in which the hole size parameter r makes its appearance. For r equals 1, the results reduce to the zeroorder FowlerGuggenheim results; it is pointed out that certain symmetry properties no longer obtain when r exceeds 1. The theory is compared with experimental work on certain types of adsorbentadsorbate systems. (Author)
