$A$ plot of $\log (x / m)$ versus $\log (P)$ for the adsorption of a gas on a solid gives a straight line with a slope of:

The graph given below shows the relationship between the extent of adsorption $(x / m)$ and pressure at different temperatures. The correct order of temperatures for curves $i$, $ii$, and $iii$ is:

What is used to adsorb the poisonous gas obtained from the coal mine?

Which one of the following equations represents the Freundlich adsorption isotherm?

The correct statement for both the processes of physisorption and chemisorption is

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.
