A) \[{{N}_{2}}\]
B) \[C{{O}_{2}}\]
C) \[C{{H}_{4}}\]
D) \[{{H}_{2}}\]
Correct Answer: B
Solution :
The amount of gas adsorbed by a solid depends on the nature of gas. More easily liquefiable gas, i.e., gases with higher critical temperature are readily adsorbed as Van der Waals forces are stronger near the critical temperature for \[\begin{align} & Gas:\,\,\,\,\,\,{{N}_{2}}\,\,\,\,\,\,{{H}_{2}}\,\,\,\,\,C{{O}_{2}}\,\,\,\,C{{H}_{4}} \\ & {{T}_{c}}(K):\,\,126\,\,\,\,33\,\,\,\,\,\,\,304\,\,\,\,\,\,190 \\ \end{align}\] Hence, the correct option is [b].
