The exact solutions for thermodynamic functions as well as for the collective diffusion coefficient of an interacting linear rigid adsorbate in a one- dimensional lattice are presented. Using this result and a connectivity ansatz we proposed a model of adsorption to analyze the deposition of non- interacting k- mers on heterogeneous two- dimensional substrates. Comparison with experimental isotherms of ,  and  adsorbed on zeolites 5A and 10X are also presented.
