Carbon Monoxide Oxidation over Chromium Sesquioxide. III. Kinetics of the Reaction

Based on the experimental findings in Parts I and II, mechanisms of carbon monoxide oxidation over a-Cr2O3were proposed with which the reaction takes place simultaneously through two parallel reaction paths. Overall reaction consists of five elementary steps, and the rate constants of all ellementary stepes were determined from the analysis of appropriate transient response data. The simulation of transient response with these rate constants proved the validity of these mechansims and the results of kinetic analyses.
