    If \[{{V}_{H}},{{V}_{N}}\] and \[{{V}_{O}}\] denotes the root mean square velocity of molecules of Hydrogen, Nitrogen and Oxygen respectively at a given temperature then.

    A)  \[{{V}_{H}}>{{V}_{N}}>{{V}_{O}}\]    

    B)  \[{{V}_{H}}={{V}_{N}}={{V}_{O}}\]

    C)  \[{{V}_{H}}<{{V}_{N}}<{{V}_{O}}\]             

    D)  \[{{V}_{N}}>{{V}_{O}}>{{V}_{H}}\]

    Correct Answer: A

    Solution :

    at T = constant \[\Rightarrow \] \[{{v}_{rms}}\propto \frac{1}{\sqrt{{{M}_{w}}}}\]
