Discuss the mechanism of heterogeneous catalysts.

Explanation

Adsorption theory of heterogeneous catalysis : Adsorptifin theory explains the mechanism of heterogeneous cata-lysis .
`to` The modern adsorption theory is the combination of the intermediate compound formation theory and the old adsorption theory.
`to` The mechanism of catalysis involves five steps.

`to ` Diffusion of the reactants t‹o the surface of the catalyst.
`to` Adsorption of the reactant molecules on the surface of the catalyst .
`to` Occurrence of chemical reaction on the catalyst's surface through formation of an intermediate
`to` Desorption of reaction products from the catalyst surface, the thereby making the surface available again for more reaction of occur.
`to` Diffusion of reaction products away from the catalyst's surface.
