Gases possess characteristic critical temperature which depends upon the magnitude of intermolecular forces between the particles. Following are the critical tempeatures of some gases. From the above data what would be the order of liquefaction of these gases? Start writing the order from the gas liquefying first.

A

`H_2, He , O_2 , N_2`

B

`He, O_2, H_2, N_2`

C

`N_2, O_2, He, H_2`

D

`O_2, N_2, H_2, He`

Text Solution

Verified by Experts

The correct Answer is:
D
Higher the critical temperature, more easily is the gas liquefied. Hence, order of liquefaction starting with the gas liquefying first will be `O_2, N_2, H_2, He`

{:("Gas",H_(2),He,O_(2),N_(2)),("Critical temp. ink",33.2,5.3,154.3,126):} From the above data, what would be the order of liquefication of these gases? Start writing the order for the gas which liquefies first:

Assertion: A gas with higher critical temperature gets adsorbed to more extent than a gas with lower critical temperature. Reason: The easily liquefiable gases get adsorbed to more extent which have higher critical temperature.

Assertion : Lower the cirtical temperature for a gas, more easily can it is liquefied. Reason : Critical temperature is the temperature above which above which a gas cannot liquefied depending upon the pressure.
