Question

A gas undergoes physical adsorption on a surface and follows the given Freundlich adsorption isotherm equation x/m = kp 0.5

Adsorption of the gas increase with : 

(1) Decrease in p and increase in T 

(2) Increase in p and decrease in T 

(3) Decrease in p and decrease in T 

(4) Increase in p and increase in T

Answer 1

Correct option (2) Increase in p and decrease in T

Explanation:

Increase in Pressure leads to the increase in adsorption capacity And the physical adsorption is an exothermic process with the increase in temperature adsorption decrease.
