Given below are the critical temperatures of some of the gases:
| Gas | Critical temperature (K) |
|---|---|
| He | 5.2 |
| CH$_4$ | 190.0 |
| CO$_2$ | 304.2 |
| NH$_3$ | 405.5 |
The gas showing least adsorption on a definite amount of charcoal is
Solution
The greater the value of critical temperature greater is adsorption as He has the least critical temperature so it
adsorb least.
