Abstract

The thermal dissociation of molecular CO adsorbed on the Mo(001) surface has been studied using ultraviolet photoemission methods. Results derived from isothermal measurements indicate that the conversion to atomic β-CO does not obey simple first order kinetics. The observed rate behavior can be explained, however, by an activation energy which increases with adsorbate coverage from a value of 0.60 eV near half coverage. Adsorbate-induced rearrangement of Mo atoms may be responsible for the coverage-dependent changes in the reaction rate.
