While it may appear that little difference in form exists between Langmuir-Hinshelwood rate expressions and those of Hougen-Watson, it must be emphasized that the developments of Watson and Hougen prove to be far more comprehensive. For in addition to surface reaction per se, the Hougen- Watson formulations include explicit terms for catalyst activity (sites), catalyst effectiveness due to diffusion, and provision for activity decay. Further, multisite as well as adjacent- site models were anticipated. The Hougen-Watson catalytic rate equations represent not merely a modification of the Langmuir-Hinshelwood formulations but highly instructive extensions and refinements, the unique utility of which is demonstrated in the analysis and design of catalytic reactors.
