On the basis of data given below predict which of the following gases shows least adsorption on a definite amount of charcoal?
`{:("Gas" ,,CO_(2),,SO_(2),,CH_(4),,H_(2)),("Critical temp./K",,304,,630,,190,,33):}`

A

`CO_2`

B

`SO_2`

C

`CH_4`

D

`H_2`

Text Solution

Verified by Experts

The correct Answer is:
D
Higher critical temperatures indicate easily liquefiable gases which are readily adsorbed as the van der Waal.s forces responsible for adsorption of gases on solid surfaces are stronger near critical temperatures.
