The vander waal's constant "a" for gases P,Q,R and S are 4.17 , 359 . 6.71 & 3.8 atm `L^(2) " mol"^(-2)` . Therefore , the ascending order of their ease of liquefaction is :-

A

`RltPltSltQ`

B

`QltSltRltP`

C

`QltSltPltR`

D

`RltPltQltS`

Text Solution

Verified by Experts

The correct Answer is:
C
Easily liquefiable gases have greater intermolecular forces which is represented by high value of .a.. The greater the value of.a. more will be liquefiability.
So, the order is Q < S < P < R.
