Which is not correct regarding the adsorption of a gas on surface of a solid?

A

It is reversible in nature

B

Adsorption is more for some specific substance

C

On increasesing temperature, adsorption increases continuosly

D

Enthalpy and entropy changes are negative

Text Solution

Verified by Experts

The correct Answer is:
C
In case of physical adsorption, extent of adsorption `(x//m)` decreases with increase of temperature while in case of chemial adsorption `(x//m)` increases first, reaching to a maximum and then decreasing.
