Abstract : It is often difficult to compare results for heterogeneous reactions as the data reported in the literature are presented in various ways. A common example of this difficulty is the reporting of oxygen adsorption rate constants in various units. In the paper a number of studies involving oxygen interchange with vanadium pentoxide or vanadium pentoxide - potassium sulfate promoted catalysts are re-examined. Where possible, a first-order oxygen adsorption rate constant is evaluated from published data on rates of oxidation and rates of isotopic exchange, and expressed in units of 1/h-sq m of catalyst surface. The rate constants so evaluated and compared as to catalyst composition, temperature, and activation energy show reasonable agreement, even though a variety of catalysts, processes, and techniques are involved.
