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:

During the process of adsorption,

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: $\log 2 = 0.3010$.

Which of the following statements is true regarding chemisorption?

$A$ 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

The plot that best represents the relationship between the extent of adsorption $(x / m)$ and pressure $(p)$ is
