The Vander Waal’s constant ‘a’ for the gases `O_(2), N_(2), NH_(3)` and `CH_(4)` are 1.3, 1.390, 4.170 and `2.253 l^(2)"atm" "mol"^(-2)` respectively. The gas which can be most easily liquefied is

A

`O_(2)`

B

`N_(2)`

C

`NH_(3)`

D

`CH_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
Value of constant a is greater than other for `NH_(3)` that.s why `NH_(3)` can be most easily liquefied .
