# In Reference to Freundlich Adsorption Isotherm, Write the Expression for Adsorption of Gases on Solids in the Form of an Equation. - Chemistry

In reference to Freundlich adsorption isotherm, write the expression for adsorption of gases on solids in the form of an equation.

#### Solution

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.
