Solution

## Freundlich Adsorption Isotherm“Freundlich, in $1909$, gave an empirical relationship between the quantity of gas adsorbed by unit mass of solid adsorbent and pressure at a particular temperature.”Equation given by Freundlich The relationship can be expressed as follows:- $\frac{x}{m}=k{p}^{1}{n}}\left(n>1\right)$Here, $x$ is the mass of the gas adsorbed, and mass $m$ of the adsorbent at pressure $p$.$k$ and $n$ are constants that depend on the nature of the adsorbent and the gas at a particular temperature.Use of Freundlich adsorption isotherm plotIt is utilized for the low-pressure adsorption of gases by solids.
