Abstract
Velocity distributions of desorbing product CO, in CO oxidation on Pt( 133) were analyzed in both the active and inhibited regions at the ste ady state. The translation temperature is high in the active region wh ere the reaction is in the first order with respect to CO. It decrease s sharply with increasing CO pressure when the reaction shifts to the inhibited region where CO retards the reaction. The translational ener gy of CO, increases linearly with the surface temperature. (C) 1998 El sevier Science B.V. All rights reserved.
