Whenever a mixture of gases is allowed to come in contact with a particular adsorbent under the same conditions, the more strong adsorbate is adsorbed to greater extent irrespective of its amount present, e.g. H2O is adsorbed to more extent on silica gel than N2 and O2. This shows that some adsorbates are preferentially adsorbed. It is also observed that preferentially adsorbable adsorbent can displace a weakly adsorbed substance from the surface of an adsorbent.
Q.
Which of the gas can displace remaining all the gases.
- a)O2
- b)N2
- c)CO
- d)H2
Correct answer is option 'C'. Can you explain this answer?

Gas Adsorption and Preferential Adsorption
Gas adsorption is the process by which gas molecules adhere to the surface of a solid material, known as an adsorbent. The extent of adsorption depends on various factors, including the nature of the adsorbate (gas) and the adsorbent.
Preferential Adsorption
Preferential adsorption refers to the phenomenon where a certain gas is adsorbed to a greater extent compared to other gases when in contact with the same adsorbent under the same conditions. In the given scenario, it is observed that H2O (water) is adsorbed to a greater extent on silica gel compared to N2 (nitrogen) and O2 (oxygen).
Displacement of Weakly Adsorbed Substance
It is also observed that a preferentially adsorbed gas can displace a weakly adsorbed substance from the surface of an adsorbent. This means that if a gas is preferentially adsorbed on an adsorbent, it can replace or displace another gas that is weakly adsorbed.
Gas that can Displace Remaining Gases
In the given options, the gas that can displace all the remaining gases is CO (carbon monoxide). This is because CO has a stronger adsorption affinity compared to the other gases mentioned (O2, N2, and H2).
When CO comes in contact with an adsorbent, it will be preferentially adsorbed to a greater extent compared to the other gases present. As a result, CO can displace the weakly adsorbed substances (N2, O2, and H2O) from the surface of the adsorbent.
Therefore, option C, CO, is the correct answer as it has the ability to displace all the remaining gases (N2, O2, and H2) due to its preferential adsorption on the adsorbent.
