Basing on the rigorous microscopical description, the statistical theory for magnetoactive particles near the metal surface characterized by certain adsorption potential is being established. Taking into account magnetic exchange and dipole interaction assures validity of the model for the description of CO oxidation on the metal surface reaction kinetics. The set of transport equations for the "density-density", "spin-spin", "(spin) structure factor-(spin) structure factor" diffusion processes is obtained. The given system is analyzed for the case of weak nonequilibrium.
