Solution

The correct option is C 1 : 1
Average $K E$ per mole at same temperature $= 1 : 1$
$K E \propto T$
Average $K E$ per mole depends on temperature only.

Three closed vessels A, B and C are at the same temperature T and contain gases which obey Maxwell distribution law of velocities. Vessel A contains $O_{2}$ , B only $N_{2}$ and C mixture of equal quantities of $O_{2}$ and $N_{2}$ . If the average speed of $O_{2}$ molecules in vessel A is $V_{1}$ and that of $N_{1}$ molecules in vessel B is $V_{2}$ , then the average speed of the $O_{2}$ molecules in vessel C is
