    At what temperature will the RMS velocity of \[S{{O}_{2}}\]be the same as that of \[{{O}_{2}}\] at 303 K?

    A)  606 K    

    B)  273 K

    C)  403 K            

    D)  303 K

    Correct Answer: A

    Solution :

    rms velocity \[=\sqrt{\frac{3RT}{M}}\] \[{{\left( \sqrt{\frac{3RT}{{{M}_{1}}}} \right)}_{{{O}_{2}}}}={{\left( \sqrt{\frac{3RT}{{{M}_{2}}}} \right)}_{S{{O}_{2}}}}\] \[\sqrt{\frac{303}{32}}=\sqrt{\frac{T}{64}}\] \[T=\frac{303\times 64}{32}=606\,K\]
