Adsorption of atom and radical particles

As it has been shown in Section 1.11 a comparison of experimental data on effects of adsorption of various particles on electric conductivity of oxide adsorbents results in conclusion that the dominant role in this 

On the contrary such active particles as hydrogen atoms and metals (electron donors), touching the surface of oxides dopes them increasing the surface concentration of electron donors which results in increase in adsorbent conductivity. 

Taking into account above considerations for the rate of the change in concentration of chemisorbed radicals forming unstable organometal surface compounds we obtain the following expression 

The first term k Ny Nso Ns) describes the rate of formation of adsorbed complexes . . Mef ) ] Ny is the concentration of 

The second and third terms in equation (2.86) describe kinetics of annihilation of radicals corresponding to above processes developing in the first and second order of magnitude with respect to chemisorbed radicals. Note that the rate constant A may be dependent on concentration of free radicals in volume.
