It is easier to liquify ammonia than oxygen because

A

it is easier to compress oxygen than `NH_(3)`

B

`NH_(3)` has a very low critical temperature as compared to `O_(2)`

C

`O_(2)` has a higher value of der Waals constant a and higher critical temperature than `NH_(3)`

D

`NH_(3)` has a higher value of van der Waals constant a and higher critical temperature than oxygen .

Text Solution

Verified by Experts

The correct Answer is:
D
`NH_(3)` has higher value of a, it means intermolecular forces are stronger and higher critical temperature than oxygen, hence easy to liquefy.
