The correct order of adsorption of the following gases on the surface of charcoal is
\(\begin{array}{llllll}\mathrm{H}_2 & \mathrm{CH}_4 & \mathrm{SO}_2 & \mathrm{H}_2 & \mathrm{CH}_4 & \mathrm{SO}_2 \\ \mathbf{I} & \mathbf{I I} & \text { III } & \mathbf{I} & \text { II } & \text { III }\end{array}\)
- A III \(>\) II \(>\) I
- B III \(>\) I \(>\) II
- C \(\mathrm{II}>\mathrm{I}>\mathrm{III}\)
- D \(\mathrm{II}>\mathrm{III}>\mathrm{I}\)
Answer & Solution
Correct Answer
(A) III \(>\) II \(>\) I
Step-by-step Solution
Detailed explanation
Higher is the critical temperature of a gas, greater is the case of liquefaction i.e., greater is the van der Waal's interaction.
