Given the following data:

Gas	$H_2$	$CH_4$	$CO_2$	$SO_2$
Critical Temp $/ K$	$33$	$190$	$304$	$630$

Based on the data provided,predict which of the following gases shows the least adsorption on a definite amount of charcoal.

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 $100 \ atm$?

For the adsorption of a solution on a solid surface,the Freundlich adsorption isotherm is given by $\frac{x}{m} = k C^{1/n}$. The plot of $\log (\frac{x}{m})$ versus $\log C$ is shown below. This corresponds to which of the following conditions?

Which of the following gases will be adsorbed to a greater extent on the surface of charcoal?

According to the Langmuir adsorption isotherm,at very high pressure,the amount of gas adsorbed $x/m$ is:

Adsorption of a gas follows the Freundlich adsorption isotherm. $x$ is the mass of the gas adsorbed on mass $m$ of the adsorbent. The plot of $\log \frac{x}{m}$ versus $\log p$ is shown in the given graph. $\frac{x}{m}$ is proportional to:
