Abstract
A theory is developed to explain the rather simple phenomenology of submonolayer adsorption on real solid surfaces in spite of the hazy situation characterizing the theoretical description of adsorption on ideal homogeneous surfaces. The situation is atypical: we cannot invoke the knowledge of the local behavior to explain the overall behavior. The new situation requires a quite new methodology. The main results of the present work consist in showing that the Freundlich and the Dubinin-Radushkevich adsorption isotherms are due to an equilibrium structure of adsorbing surfaces, this structure being that of equilibrium at their formation temperature.
