    The r.m.s. velocity of oxygen molecule at \[16{}^\circ C\] is 474 m/sec. The r.m.s. velocity in m/s of hydrogen molecule at \[127{}^\circ C\]is

    A) 1603    

    B)        1896

    C) 2230.59

    D) 2730

    Correct Answer: C

    Solution :

    [c] \[{{v}_{oxg.}}=\sqrt{\frac{3R\times 289}{32}}\] \[\left( {{v}_{rms}}=\sqrt{\frac{3RT}{M}} \right)\] \[{{v}_{H}}=\sqrt{\frac{3R\times 400}{2}}\]so \[{{v}_{H}}=2230.59\,m/\sec \]
