Q25 / 160 · AP EAMCET 2024 (21 May Shift 1) · Chemistry

The correct statement regarding chemisorption is

A
It is a multilayered adsorption
B
The process is reversible in nature
C
The process is not specific in nature
Correct answer
D
Enthalpy of adsorption is in the range of 80-240 kJ $\mathrm{mol}^{-1}$

Solution

Chemisorption: (i) It is highly specific in nature. (ii) It is irreversible (iii) It result into unimolecular layer. (iv) Enthalpy of adsorption is high ( $80-240 \mathrm{~K}$ ) (v) It is caused by chemical bond formation.

Hence, the correct answer is option: 'D'.
