Question

Heterogeneous catalysis is successfully explained by ____.

• A. adsorption theory
• B. desoption theory
• C. absorption theory
• D. none of the above

Answer 1

The correct option is A adsorption theory

Heterogeneous catalysis is successfully explained by adsorption theory
Catalyst surface has free valencies which provides sites for chemical forces of attraction. The gaseous or solution phase reactants are adsorbed on catalyst surface. The bonds in reactant molecules break easily. Hence, the reaction quickly proceeds.
