Four gases $A$,$B$,$C$,and $D$ have critical temperatures $5.3 \ K$,$33.2 \ K$,$126.0 \ K$,and $154.3 \ K$ respectively. For their adsorption on a fixed amount of charcoal,the correct order is:

If $x$ is the mass of the gas adsorbed on mass $m$ of the adsorbent at pressure $p,$ Freundlich adsorption isotherm gives a straight line on plotting

$3 \, g$ 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: .............. $mg$

When a dilute aqueous solution of $AgNO_3$ (excess) is added to $KI$ solution,positively charged sol particles of $AgI$ are formed due to the adsorption of which ion?

The charge of $As_2S_3$ sol is due to the adsorption of

Arrange the gases $H_2, CH_4, CO_2,$ and $NH_3$ in the order of their volume adsorbed on $1 \ g$ of charcoal at $288 \ K$.
