Question 1 :
The adsorption of a gas, on a solid surface, varies with pressure of the gas in which of the following manner?

Question 4 :
The process of adsorption of hydrogen over palladium surface is called:

Question 7 :
Which gas will be absorbed on a solid to greater extent?

Question 8 :
Silica gel is used for keeping away the moisture because it?

Question 11 :
In physisorption adsorbent does not show specificityfor any particular gas because:

Question 14 :
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. For example, $H_2O$ is adsorbed to more extent on silica gel than $N_2$ and $O_2$. This shows that some adsorbates are preferentially adsorbed. It is also observed that preferentially adsorbable adsorbents can displace a weakly adsorbed substance from the surface of an adsorbent.<br/>Which of the gas can displace remaining all the gases?
