Ncert Exercises & Solutions

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

1. I $\to$ II $\to$ III $\to$ IV $\to$ V

2. I $\to$ III $\to$ II $\to$ IV $\to$ V

3. I $\to$ III $\to$ II $\to$ V $\to$ IV

4. I $\to$ II $\to$ III $\to$ V $\to$ IV

Correct sequence is I

\to

III

\to

\to

\to

Each transformation denotes a meaningful process as follows

I → adsorption of A and B on surface

III → II interaction between A and B to form intermediate

II → IV starting desorption of A - B

IV → V complete desorption
