Under what conditions does the rate of physisorption increase?

Which of the following is not a favourable condition for physical adsorption?

Physical adsorption is inversely proportional to the

In the Freundlich isotherm $\frac{x}{m}=k p^{\frac{1}{n}}$ plot of $\log \frac{x}{m}$ vs $\log p$, the intercept is (where, $x$, $m$, $p$ and $k$ are mass of the gas, mass of adsorbent, pressure and constant which depend on the nature of the adsorbent, respectively)

Assertion : The relation $\frac{x}{m} = k \cdot p^{1/n}$ is known as Freundlich adsorption isotherm,where $x$ is the mass of gas adsorbed by $m$ grams of adsorbent,$p$ is the equilibrium pressure,$k$ and $n$ are constants for a given system and temperature.
Reason : When several substances have the same value of $\frac{1}{n}$,the lines by which their adsorption isotherms can be represented will meet at a point.

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
