Solution

Freundlich adsorption isotherm for adsorption of gases on solids:
xm=Kp1nIt can also be written aslogxm=log K + 1nlog p">

\[\frac{x}{m} = K p^\frac{1}{n} \]

\[\text{It can also be written as}\]

\[\log\frac{x}{m} = \log K + \frac{1}{n}\log p\]

where x is the mass of the adsorbate, m is the mass of the absorbent and p is the pressure of the gas and n is a constant which is greater than 1.
