Solution

The correct option is B

For a given $M$ , $v_{a v} \propto \sqrt{T}$ only. Therefore, the correct choice is $v_{1}$ as the temperature of vessels $A$ and $C$ are the same.

Three closed vessels A, B and C are at the same temperature. Vessel A contains only O2 B only N2 and C a mixture of equal quantities of O2 and N2. If the average speed of O2 molecules in vessel A is v1, that of O2 molecules is vessel C is

The correct option is B For a given M, vav ∝ √T only. Therefore, the correct choice is v1 as the temperature of vessels A and C are the same.
