For real gases van der Waals equation is written as
(V - nb) = nRT
where ′a′ and ′b′ are van der Waals constants.
I. O2, CO2, H2 and He
II. CH4, O2 and H2
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:
(V - nb) = nRTwhere ′a′ and ′b′ are van der Waals constants.
I. O2, CO2, H2 and He
II. CH4, O2 and H2
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:
Options
A.(I) H2 < O2 < He < CO2 (II) O2 > CH4 > H2
B.(I) He < H2 < CO2 < O2 (II) CH4 > H2 > O2
C.(I) O2 < He < H2 < CO2 (II) H2 > O2 > CH4
D.(I) H2 < He < O2 < CO2 (II) CH4 > O2 > H2
Solution
