From Freundlich adsorption isotherm, if $\log \frac{\mathrm{x}}{\mathrm{m}}$ is plotted in $\mathrm{y}$-axis and $\log \mathrm{p}$ in $\mathrm{x}$-axis, the slope will be (Where $\text{'}\mathrm{k}\text{'}$ and $\text{'}\mathrm{n}\text{'}$ are constants that depend on the nature of the adsorbent and the gas at a particular temperature, $\text{'}\mathrm{x}\text{'}$ is the mass of gas adsorbed on mass $\text{'}\mathrm{m}\text{'}$)

The extent of physical adsorption of a gas increases with
