We present generalized transfer equations for the consistent description of electron kinetic and atomic diffusion processes in a system ‟metal–adsorbat–gas–tip”. These equations were obtained with the use of the method of the nonequilibrium statistical operator by D. N. Zubarev. We also obtain the kinetic equation for a one–electron density matrix as well as generalized diffusion equations for adsorbed and non–adsorbed gas atoms on a metal surface. These equations are analysed for both strongly and weakly non–equilibrium processes.
