Resumen:
The adsorption-desorption kinetics with multiple site occupation in a one-dimensional network is formulated in the framework of the kinetic
lattice gas model. The kinetic equations that describe the time evolution of the correlators are obtained by use of the so called Local Evolution
Rules, that take into account the adsorption, desorption, and diffusion of the adsorbed molecules. After truncating the infinite hierarchy of
equations, different cases are analyzed. Equilibrium solutions are obtained and the exact expression for adsorption isotherms as well as the
nearest-neighbor correlations are presented. The asymptotic approach to the equilibrium is also discussed. Finally, we analyzed the desorption
kinetics throughout the thermal desorption spectra.
