Solution

The correct option is C $N H_{3}$
The amount of gas adsorbed depends upon the nature of the gas.
$Extent of adsorption \propto Critical temparature$
The critical temperature follows the order:
$N H_{3} > N_{2} > O_{2} > H_{2}$
Therefore option $A$ is the correct answer.

Q. Whenever a mixture of gases is allowed to come in contact with a particular adsorbent under the same conditions, the more strong adsorbate is adsorbed to greater extent irrespective of its amount present. For e.g.

H_{2} O

is adsorbed to a greater extent on silica gel than

N_{2}

O_{2}

. This shows that some adsorbates are preferentially adsorbed. It is also observed that preferentially adsorbable adsorbents can displace a weakly adsorbed substance from the surface of an adsorbent. Which of the following gase(s) is/are adsorbed to maximum extent?
