Greater the critical temperature of a gas, greater is the adsorption. Critical temperatures are as follows:

N H_{3} (406 K), C O_{2} (304 K), C H_{4} (190 K)

and

H_{2} (33 K)

Thus, adsorption decreases from

N H_{3}

to

H_{2}

in this order :

N H_{3} > C O_{2} > C H_{4} > H_{2}

Q. The volumes of gases $H_{2}, C H_{4}, C O_{2}$ and $N H_{3}$ adsorbed by $1 g$ of charcoal at $298 K$ are in the order

$H_{2} > C H_{4} > C O_{2} > N H_{3}$

$C H_{4} > C O_{2} > N H_{3} > H_{2}$

$C O_{2} > N H_{3} > H_{2} > C H_{4}$

$N H_{3} > C O_{2} > C H_{4} > H_{2}$

Greater the critical temperature of a gas, greater is the adsorption. Critical temperatures are as follows:

$N H_{3} (406 K), C O_{2} (304 K), C H_{4} (190 K)$ and $H_{2} (33 K)$

Thus, adsorption decreases from $N H_{3}$ to $H_{2}$ in this order :

$N H_{3} > C O_{2} > C H_{4} > H_{2}$
