Question

Arrange the following gases in increasing order of tendency of adsorption.

H₂ < 02 < CO₂ < SO₂

H₂> 0₂ > CO₂ > SO2

SO₂ CO₂ <0₂ <H₂

CO₂SO₂ <0₂ <H₂​

Answer 1

Answer:

The first option is correct- $H_{2} < O_{2} < CO_{2} < SO_{2}$.

Explanation:

• The adsorption of any gas will be directly proportional to its critical temperature.
• A critical temperature is a temperature above which the gas cannot be liquefied regardless of how high the pressure is.
• The higher the critical temperature higher would be the adsorption.
• The lower the critical temperature lower would be the adsorption.
• $SO_{2}$ has the highest critical temperature and $H_{2}$ has the lowest critical temperature. The former has the highest extent of adsorption and the latter has the least.
