Freundlich isotherm is related with the pressure of gas adsorbed, as follows $\frac{\mathrm{x}}{\mathrm{m}}=\mathrm{k}·{\mathrm{p}}^{1/\mathrm{n}}$

where, $\frac{\mathrm{x}}{\mathrm{m}}=$ amount of gas $\left(\mathrm{x}\right)$ adsorbed over the surface of mass $\left(\mathrm{m}\right)$.

$\mathrm{p}=$ pressure of gas

$\mathrm{k}=$ freundlich constant

Thus, value of $\text{'}\mathrm{n}\text{'}$ is always greater than 1 and therefore value of $1/\mathrm{n}$ lies between $0$ and $1$.
