Question

Arrange the following diagrams in correct sequence of steps involved in the mechanism of catalysis, in accordance with modern adsorption theory.

                    (a)

             (b)

           (c)

               (d)

               (e)

Options

• \[\ce{a → b → c → d → e}\]

• \[\ce{a → c → b → d → e}\]

• \[\ce{a → c → b → e → d}\]

• \[\ce{a → b → c → e → d}\]

Answer 1

\[\ce{a → c → b → d → e}\]

Explanation:

The correct sequence of steps involved in catalysis are:

(i) Adsorption of A and B on surface

(ii) Interaction between A and B to form intermediate

(iii) Starting of desorption from surface

(iv) Complete desorption from the surface
