The gas that is adsorbed to a larger extent on charcoal is

A

`H_(2)`

B

`CO_(2)`

C

CO

D

`NH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
It is seen that, higher the critical temperature of the gas, more easily it can be liquified, i.e. greater are the intermolecular forces of attraction of gaseous molecules on the surface of adsorbent. Hence, greater will gbe the adsorption.
`{:("Gas",, "Critical temperature"),(H _ 2,,4.7 ) , ( CO _ 2,,4.8),(CO,,9.3),(NH_3 ,, 181):} `
Hence, ` NH _ 3 ` is adsorbed to a larger extent on charcoal.

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. H_(2)O 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 adsorbent can displace a weakly adsorbed substance from the surface of an adsorbent. Which of the gas can displace remaining all the gases.

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. Preferential adsorption depends on strength of attraction, surface area, polar nature and other factors. Which of the following isomer of C_(6)H_(14) is adsorbed to maximum extent?
