Abstract

For the adsorption of gases on a solid surface we derive equations for the low-temperature adsorption isotherms, isosteric heats of adsorption, and heat capacities of the adsorbed phase for both a patchwise and a random surface topography. A model of localized monolayer adsorption with nearest neighbor interactions between admolecules is used. The equations are illustrated by appropriate model calculations.
