Q. The correct option(s) related to adsorption processes is(are)
JEE Advanced
JEE Advanced 2022
A
Chemisorption results in a unimolecular layer.
95%
B
The enthalpy change during physisorption is in the range of 100 to $140\, kJ\, mol ^{-1}$.
5%
C
Chemisorption is an endothermic process.
37%
D
Lowering the temperature favors physisorption processes.
153%
Solution:
(A) Chemisorption is unimolecular layered.
(B) Enthalpy of physisorption is much less in magnitude.
(C) Chemisorption of gases on solids is exothermic.
(D) As physisorption is exothermic so lowering temperature favours it.
