Which one of the following is not a property of physical adsorption ?

A

Higher the pressure, more the adsorption

B

Greater the surface arca, more the adsorption

C

Lower the temperature, more the adsorption.

D

Unilayer adsorption occurs

Text Solution

Verified by Experts

The correct Answer is:
D
The physical adsorption is temperature and pressure dependent. It increases with increase in pressure and decreases with increase in temperature. Also, when there is more surface area then physical adsorption will be more. Physical adsorption forms multiple layer of adsorption. Thus, statement given in option (d) is incorrect.
