On the basis of data given below predict which of the following gases shows least adsorption on a definite amount of charcoal?
Gas
$$C{O_2}$$
$$S{O_2}$$
$$C{H_4}$$
$${H_2}$$
Critical temp./$$K$$
304
630
190
33
A.
$$C{O_2}$$
B.
$$S{O_2}$$
C.
$$C{H_4}$$
D.
$${H_2}$$
Answer :
$${H_2}$$
Solution :
More easily liquefiable gases are adsorbed readily. Thus, $${H_2}$$ gas having low critical temperature $$\left( {33\,K} \right)$$ is not easily liquefied and shows least adsorption.
