Vedclass · Answer

(B) The root-mean-square velocity $(v_{rms})$ of gas molecules is given by the formula: $v_{rms} = \sqrt{\frac{3RT}{M}}$.At a given temperature $(T)$,$v_{rms} \propto \frac{1}{\sqrt{M}}$,where $M$ is the molar mass of the gas.The molar masses are: $M_H = 2 	ext{ g/mol}$,$M_N = 28 	ext{ g/mol}$,and $M_O = 32 	ext{ g/mol}$.Since $M_H  \frac{1}{\sqrt{M_N}} > \frac{1}{\sqrt{M_O}}$.Therefore,the relationship between the velocities is ${V_H} > {V_N} > {V_O}$.

If ${V_H}$,${V_N}$,and ${V_O}$ denote the root-mean-square velocities of molecules of hydrogen,nitrogen,and oxygen respectively at a given temperature,then:
