Amount of gas adsorbed per gram of adsorbent increases with pressure, but after a certain limit is reached, adsorption becomes constant. It is where

A

multilayers are formed

B

desorption takes place

C

temperature is increased

D

adsorption also starts

Text Solution

Verified by Experts

The correct Answer is:
A
Langmuir showed that at low pressure, the physically adsorbed gas forms only one a certain one molecule thick layer. However, above a certain pressure , multimolecular thick layer is formed.
