Adsorption of a gas follows Freundlich adsorption isotherm. In the given plot,x is the mass of the gas adsorbed on mass m of the adsorbent at pressure `P." "(x)/(m)` is proportional to:

A

1.`P^(1//2)`

B

2.`P`

C

3.`P^(1//4)`

D

4.`P^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
According the Freundlich adsorption isotherm
`x/m=kp^(1//n) :. "log" x/m=logk+1/n log p`
According to the graph slope `=2/4=1/2 :. n=2:.x/m prop p^(1//2)`
