Question

During the operation of an industrial heterogeneous catalyst, what is the critical kinetic consequence if the absolute heat of chemisorption between the products and the active sites is excessively high?

Prashant Kotian · Accepted Answer

Correct answer: C. For a heterogeneous catalyst to function continuously, the products must rapidly desorb to free the active sites for fresh reactants. If the products chemisorb too strongly (excessively high binding energy), they act as permanent localized poisons, totally stopping the industrial process.
