A graph drawn between ${ }^{\mathrm{\prime }}{\log }^{\mathrm{\prime }} \frac{\mathrm{x}}{\mathrm{m}}$ and log p on ‘X’ and ‘Y’ axis respectively could be a regarding physical adsorption

Freundlich adsorption isotherm is,  $\log (\mathrm{x}/\mathrm{m}) = (1/\mathrm{n}) \mathrm{logP} + \mathrm{logK}$.

The graph drawn between ${ }^{\mathrm{\prime }}{\log }^{\mathrm{\prime }} \frac{\mathrm{x}}{\mathrm{m}}$ and log p on ‘X’ and ‘Y’ axis respectively is a straight line with slope 1/n (positive slope)
