Kinetics of oxygen adsorption on silver films

Kinetics of oxygen adsorption on silver films prepared by metal vacuum evaporation and condensation technique has been studied. The adsorption proceeds in accordance with the kinetic law of Zeldovich-Roginskii. Oxygen dissolution in the silver subsurface layers result in a decrease of the initial adsorption rate and an enhanced exponential decrease of the adsorption rate as a function of surface coverage.
