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.
