✦ Synopsis

Shorter Corn] munications more than one rate controlling step exists should be particularly useful. This concept, originated by Horiuti [4,5], has been extended to include rate controlling paths by Happel[6]. A recent study [7] employed 14C as a tracer to demonstrate the applicability of a reaction rate expression of the following form to butane dehydrogenation: ethanol could be treated in an entirely similar way. The obtaining of a stoichiometric number of unity with '% as a tracer would be tantamount to proving that hydrogen desorption or adsorption is not rate controlling. Then a potential term could be extracted as in the case of butane dehydrogenation with consequent simplification. We believe that in modeling of chemical reactions both experimental and mathematical approaches can be advantageously combined in this fashion, though this has rarely been done in the past.
