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

$A$ mixture of gases $O_2$,$H_2$,and $CO$ are taken in a closed vessel containing charcoal. The graph that represents the correct behaviour of pressure with time is

Adsorption of a gas on an adsorbent follows Freundlich adsorption isotherm. The slope and intercept (on $y$-axis) of the isotherm are $0.5$ and $1.0$ respectively. What is the value of $\frac{x}{m}$,when the pressure of the gas $(p)$ is $100 \ atm$?

Which of the following phenomena is inversely proportional to adsorption?

Statement $I$: Silica gel and alumina are used as adsorbents for adsorption chromatography.
Statement $II$: Paper chromatography is a type of partition chromatography.
In the light of the above statements,select the correct option.

For the adsorption of a gas on a solid adsorbent,which of the following is positive?
