Wood charcoal is used in gas masks because...

The adsorption of a gas on the surface of a solid is generally an exothermic process because ......

In the figure,a straight line is given for the Freundlich Adsorption isotherm equation $(y = mx + c)$,where the equation is $y = 0.3x + 0.7033$. The values of $\frac{1}{n}$ and $\log K$ are respectively:

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 statements is incorrect?

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)
