Adsorption of a gas follows the Freundlich adsorption isotherm. In the given plot,$x$ is the mass of gas adsorbed on mass $m$ of the adsorbent at pressure $p$. $\frac{x}{m}$ is proportional to:

Which one of the following is not the correct characteristic property of physical adsorption?

$3 \, g$ of activated charcoal was added to $50 \, mL$ of acetic acid solution $(0.06 \, N)$ in a flask. After an hour,it was filtered and the strength of the filtrate was found to be $0.042 \, N$. The amount of acetic acid adsorbed (per gram of charcoal) is: .............. $mg$

$CO_{2}$ gas adsorbs on charcoal following Freundlich adsorption isotherm. For a given amount of charcoal,the mass of $CO_{2}$ adsorbed becomes $64$ times when the pressure of $CO_{2}$ is doubled. The value of $n$ in the Freundlich isotherm equation is $......\,\times 10^{-2}$. (Round off to the Nearest Integer)

The extent of adsorption of a gas on a solid depends on:

The critical temperatures of gases $A, B, C,$ and $D$ are $190 \ K, 630 \ K, 261 \ K,$ and $400 \ K$ respectively. The quantity of gas adsorbed per gram of charcoal at the same pressure is least for the gas:
