It has been known for a long time that the topography of surface is a very important factor governing the adsorption on heterogeneous solid surfaces. In spite of this.all methods to evaluate the adsorptionencrgy distribution,developed so far were based on the patchwise model of heterogeneous surfaces. The purpose of this paper is to show how the well-known condensation approximation method can be applied to determine the adsorption energy distribution on the hctcrograph surfaces with a fully random topographical distribution of sites. The method is developed for the case of localized adsorption with nearest-neighbour interaction between bimolecules.
