Rate of physical adsorption increases with

A

decrease in temperature

B

decrease in pressure

C

increase in temperature

D

decrease in surface area

Text Solution

Verified by Experts

The correct Answer is:
A
Low temperature favours physical adsorption it decreases with increase of temperature and vice-versa.
Decrease of pressure causes desorption.
Physical adsoption varies directly with surface area, i.e. higher the surface area, miore will the be adsorption
