Question

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

• A. $a\to b\to c\to e\to d$
• B. $a\to c\to b\to d\to e$
• C. $a\to c\to b\to e\to d$
• D. $a\to b\to c\to d\to e$

Answer 1

The correct option is B $a\to c\to b\to d\to e$

Here each diagram represents a meaningful process which occurs in modern adsorption theory.

$A.$ Represents adsorption of adsorbate $A$ and $B$ on the surface

$\left(c\right)\to \left(b\right)$ represents the interaction between $A$ and $B$ to form intermediate.

$\left(d\right)\to \left(e\right)$ represents complete desorption

Therefore, option $\left(B\right)$ is only correct
