Question:

Adsorption of a gas follows Freundlich adsorption isotherm x is the mass of the gas adsorbed on mass m of the adsorbent. The plot of log xm versus log p is shown in the given graph. xm is proportional to :Ap^3/2Bp^3Cp^2/Dp^2

p^3/

p^3

p^2/

p^2

Solution:

Correct option is C. p^2/
Solution:- (C) p^2
xm=K.p^(1/n)
∴logxm=logK+(1/n).logP
slope=1/n=2/3
∴xm=K.p^(2/3)
