    Which of the following molecules has the largest root mean square velocity at \[{{25}^{o}}C\]?

    A)  \[C{{O}_{2}}\]         

    B)  \[S{{O}_{2}}\]

    C)  \[{{H}_{2}}S\]          

    D)  \[N{{H}_{3}}\]

    Correct Answer: D

    Solution :

    The largest root mean square velocity of \[{{25}^{o}}C\] is of \[N{{H}_{3}}\] because \[N{{H}_{3}}\] is of lowest molecular weight.
