Which of the following represents the Freundlich adsorption...

The equation $\dfrac{x}{m} = {KP}^{1 / n}$ represents Freundlich adsorption isotherm. It is an empirical relationship between the amount of gas adsorbed by a given amount of solid adsorbent surface and pressure of the gas at a particular temperature.

So, Freundlich adsorption isotherm equation is

$\dfrac{x}{m} = {KP}^{1 / n}$

$⇒ log\dfrac{x}{m} = logK + \dfrac{1}{n}logP$

Extent of adsorption $\left(\dfrac{x}{m}\right)$ decreases with increase in temperature.

With the help of the above two equation, following plots are obtained
