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 the critical temperature, greater is the adsorption. `H_(2)` has lowest critical temperature and hence is least adsorbed.
