For real gases van der Waals equation is written as
(P+an2V2)(V−nb)=nRT
Where 'a' and 'b' are van der Waals constants.
Two sets of gases are :
(I) O2,CO2,H2 and He (II) CH4,O2andH2
The gases given in set-I in increasing order of 'b' and gases given in set-II in decreasing order of 'a' are arranged below. Select the correct order from the following:
