Given van der Waals constant for `NH_(3), H_(2), O_(2) and CO_(2)` are respectively `4.17, 0.244, 1.36 and 3.59`, which one of the following gases is most easily liquefied?

A

`NH_3`

B

`H_2`

C

`CO_2`

D

`O_2`

Text Solution

Verified by Experts

The correct Answer is:
A
• Van der waals constant .a., signifies intermolecular forces of attraction.
• Higher is the value of .a. , easier will be the liquefaction of gas.
