Physical adsorption of a gaseous species...

Physical adsorption of a gaseous species may change to chemical adsorption with

A

Decrease in temperature

B

Increase in temperature

C

Increase in surface area of adsorbent

D

Decrease in surface area of adsorbent\

Text Solution

Verified by Experts

The correct Answer is:
B
On increasing temperature physisorption changes to chemisorption. As temperature increases, energy of activation of adsorbate particles increases which lead to formation of chemical bond between adsorbate and adsorbent.
Hence, physisorption transform into chemisorption.
