The van der Waals constants for two gase...

The van der Waals constants for two gases are as follows :
`{:("Gas",a(atm L^(2)mol^(-2)),b(L Mol^(-1))),(X,1.39,0.0391),(Y,3.59,0.0427):}`
Which of them is more easily liquefiable and which has greater molecular size ?

Text Solution

Verified by Experts

Greater the value of 'a' more easily the gas is liquefiable. Similarly, greater the value of 'b' greater is the molecular size. Hence, gas Y will be more easily liquefiable and will have greater molecular size.
