The value of van der Waals constant `a` for the gases `O_(2)`, `N_(2)`, `NH_(3)`, and `CH_(4)` are `1.360`, `1.390`, `4.170`, and `2.253 L^(2) atm mol^(-2)`, respectively. The gas which can most easily be liquefied is

A

`O_(2)`

B

`N_(2)`

C

`NH_(3)`

D

`CH_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
a. is directly related to forces of attraction. Hence greater the valueof.a., more easily the gas gets liquified.
