Chemistry Question on Ideal gas equation
Given below are the critical temperatures of some of the gases :
| Gas | Critical temperature (K) |
|---|---|
| He | 5.2 |
| CH4 | 190.0 |
| CO2 | 304.2 |
| NH3 | 405.5 |
The gas showing least adsorption on a definite amount of charcoal is
A
He
B
CH4
C
CO2
D
NH3
Answer
He
Explanation
Solution
Extent of adsorption ā TC (critical temperature)
āµ Lower the TC, Lower will be the adsorption
Hence, Helium shows least adsorption on a definite amount of charcoal.
So, the correct option is (A): He.
