The volumes of gases H(2), CH(4), CO(2) ...

The volumes of gases `H_(2), CH_(4), CO_(2)` and `NH_(3)`, adsorbed by 1 g charocal at 298 K are in the order .

A

`H_(2) gt CH_(4) gt CO_(2) gt NH_(3)`

B

`CH_(4) gt CO_(2) gt NH_(3) gt H_(2)`

C

`CO_(2) gt CO_(2) gt H_(2) gt CH_(4)`

D

`NH_(3) gt CO_(2) gt CH_(4) gt H_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
Greater the critical temperature of a gas, greater is the adsorption. Critical temperatures of the given gases are as follows: `NH_(3) (406 K), CO_(2) (304 K), CH_(4) (190 K) and H_(2) (33 K)`. Thus adsorption decreases from `NH_(3)` to `H_(2)` in this order.
