Question

Which of the following statements regarding adsorption theory of heterogeneous catalysis is not correct?

• A. The reactant molecules get adsorbed on the surface of the catalyst
• B. The chemical reaction occurs at the surface of the catalyst
• C. The product molecules remain permanently bound to the catalyst surface
• D. The catalyst remains unchanged in mass and chemical composition at the end of the reaction

Hint:

In heterogeneous catalysis, the catalyst facilitates the reaction but is not consumed and remains unchanged in its chemical composition.

Answer 1

The Correct Option is C

In heterogeneous catalysis, the catalyst adsorbs the reactant molecules, and the chemical reaction occurs at the surface. After the reaction, the product molecules are desorbed from the catalyst's surface, not permanently bound to it. Thus, the product molecules do not remain permanently bound to the catalyst.
