Solution
The correct options are A Gases A and B may be O2 and SO2 at 27oC and 327oC respectively. DTATB=MBMA For identical Maxwellian plots, the root mean square velocity for both the gases should be equal.
√3RTAMA=√3RTBMB
∴TATB=MBMA
For O2 at 27oC, Vrms=√900R32
For SO2 at 327oC, Vrms=√1800R64=√900R32
Thus the gases A and B can be O2 and SO2 at 27oC and 327oC respectively.
