The Van der Waals constants for two gase...

The Van der Waals constants for two gases A and B are as follows :
`{:("Gas",a("atm L"^(2)" mol"^(-2)),b("L mol"^(-1))),(" A"," 1.63"," 0.0326"),(" B"," 3,72"," 0.0521"):}`
Which of these
(i) is more easily liquefied?
(ii) has larger molecular size?

Text Solution

Verified by Experts

(i) Greater the value of .a. more easily the gas is liquefied. Hence gas B is more easily liquefied.
(ii) Larger the value of .b., larger is is its molecular size. Therefore, B has larger molecular size.
