Question

Heterogeneous catalysis can be explained on the basis of ______ theory.

Answer 1

Heterogeneous catalysis can be explained on the basis of adsorption theory.

Explanation:

The adsorption theory states that heterogeneous catalysis is a surface phenomenon involving the chemisorption of reactant gases on the solid catalyst's surface. This chemisorption facilitates the reaction by forming an activated complex, which then produces the products that desorb from the catalyst surface. Thus, the catalyst promotes reaction by providing active sites for adsorption and reaction on its surface.
