Q. Adsorption of a gas follows the Freundlich adsorption isotherm. In the given plot, 'x' is the mass of the gas adsorbed on mass m of the adsorbent at a pressure P.

\frac{x}{m} is proportional to

Q. Assertion :The relation

\frac{x}{m} = k . p^{1 / n}

is known as Freundlich adsorption isotherm, where

x

is the mass of gas adsorbed by

m

grams of adsorbate,

p

is the equilibrium pressure,

k

n

are constants for given system and temperature. Reason: When several substances have the same value of

\frac{1}{n}

, the lines by which their adsorption isotherms can be represented will meet at a point.

Q. On Freundlich adsorption isotherm

x

is the mass of the gas adsorbed on mass

m

of the adsorbent. The plot of
