Adparticle dynamics at a metallic surface is studied by means of quantum kinetic equations. Kinetic equations of the reaction-diffusion type are written down for nonequilibrium one-particle distribution functions of the adsorbate up to the second order in the tunnelling constants and amplitudes of chemical reactions.

Key words: quantum kinetic theory, models of surface chemical reactions, diffusion coefficient, rate constant
