Which of the following represents the Freundlich adsorption isotherm equation for the adsorption of a gas on a solid (where $n > 1$)?

When a graph is plotted between $\log (x/m)$ and $\log P$,it is a straight line with an angle of $45^o$ and an intercept of $0.3010$ on the $y-$axis. If the initial pressure is $0.3 \ atm$,what will be the amount of gas adsorbed per $g$ of adsorbent $(x/m)$?

Explain the following terms related to Adsorption Chromatography:
$(a)$ Principle of Adsorption chromatography.
$(b)$ Adsorbent.
$(c)$ Mobile phase.
$(d)$ Adsorbate.

Assertion $(A)$: Adsorption is an exothermic process.
Reason $(R)$: Physisorption of a gas on a solid surface is normally reversible.

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.

Select the graph that correctly describes the adsorption isotherms at two temperatures $T_{1}$ and $T_{2}$ $\left(T_{1}>T_{2}\right)$ for a gas :
($x-$ mass of the gas adsorbed ; $m-$ mass of adsorbent ; $P -$ pressure)
