Question

Three closed vessels A, B and C are at the same temperature and contain gases which obey the Maxwellian distribution of velocities. Vessel A contains only $O_2$, B only $N_2$, and C, a mixture of equal quantities of $O_2$ and $N_2$. If the average speed of the $O_2$ molecules in vessel A is V1, that of the $N_2$ molecules in vessel B is V2, the average speed of the $O_2$ molecules in vessel C is

Prashant Kotian · Accepted Answer

Correct answer: B. the average speed of any ideal gas species depends strictly on the absolute temperature and its own molecular mass: c_avg = √(8rt/πm). it is completely independent of the presence of other gases in a mixture. since vessel c is at the same temperature as vessel a, the average speed of o2 molecules in c is identical to that in a, which is v1.
