    At what. temperature, the rms velocity of \[\text{S}{{\text{O}}_{\text{2}}}\]be same as that of \[{{\text{O}}_{2}}\]at 303 K?

    A)  273 K            

    B)  606 K

    C) 303 K            

    D)  403 K

    Correct Answer: B

    Solution :

     \[\frac{{{U}_{rms}}(S{{O}_{2}})}{{{U}_{rms}}({{O}_{2}})}=\sqrt{\frac{T(S{{O}_{2}})}{M(S{{O}_{2}})}\times \frac{M({{O}_{2}})}{T({{O}_{2}})}}\] i.e., \[1=\sqrt{\frac{T(S{{O}_{2}})}{64}\times \frac{32}{303}}\] or \[T(S{{O}_{2}})=606\,K\]
