Question

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

A. `ItoIItoIIItoIVtoV`
B. `ItoIIItoIItoIVtoV`
C. `ItoIIItoIItoVtoIV`
D. `ItoIItoIIItoVtoIV`

Answer 1

Correct Answer - B
Correct sequence is `ItoIIItoIItoIVtoV`
Each transformation denotes a meaningful process as follows
`I to` adsorption of A and B on surface
`III to` interaction between A and B to form intermediate
`I to IV` starting desorption of A - B
`IV to V` complete desorption
