Based on a summation to infinity of the virial expansion for the 2D compressibility factor, simple equations have been developed for adsorption isotherms, and heats of adsorption, of 2D dense mobile films adsorbed on solid surfaces. They have subsequently been generalized for the presence of an external, randomly varying potential field, created by the random surface topography exhibited by heterogeneous solid surfaces.

Calorimetric Studies

The question of reversibility and equilibrium is considered in relation to the physical adsorption of gases on finely divided solid surfaces. Conclusions are drawn from calorimetric measurements of (1) adsorption isotherms, (2) integral, differential, and isosteric heats of adsorption, and (3) heat capacity of the adsorbed phase for surface coverages of the order of a monolayer or less. In line with the preceding, results are presented and discussed for calorimetric studies involving (1) heats of adsorption and heat capacities of methane adsorbed on rutile between 80 and 140°K., (2) heats of adsorption of argon on rutile between 60 and 90°K., and (3) the zero point entropy of krypton adsorbed on rutile at a coverage of about 0.57 of the monolayer capacity.
