Which one of the following gives a straight line for Freundlich adsorption isotherm?

The Langmuir adsorption isotherm is deduced using the assumption that:

Identify the $FALSE$ statement regarding adsorption from the following.

The graph of $\log \frac{x}{m}$ vs $\log p$ for an adsorption process is a straight line inclined at an angle of $45^{\circ}$ with an intercept equal to $0.6020$. The mass of gas adsorbed per unit mass of adsorbent at the pressure of $0.4 \ atm$ is $......... \times 10^{-1}$ (Nearest integer). Given: $\log 2 = 0.3010$.

In Freundlich adsorption isotherm at moderate pressure,the extent of adsorption $\left(\frac{x}{m}\right)$ is directly proportional to $P^x$. The value of $x$ is

If $x$ is the mass of the gas adsorbed on mass $m$ of the adsorbent at pressure $p,$ Freundlich adsorption isotherm gives a straight line on plotting
