    Which of the following gas will have highest rate of diffusion [Pb. CET Sample paper 1993; CPMT 1990]

    A)                 \[N{{H}_{3}}\]  

    B)                 \[{{N}_{2}}\]

    C)                 \[C{{O}_{2}}\]   

    D)                 \[{{O}_{2}}\]

    Correct Answer: A

    Solution :

               m. wt. of \[N{{H}_{3}}=17\]; m.wt. of \[{{N}_{2}}=28\]                    m.wt. of \[C{{O}_{2}}=44\]; m.wt. of \[{{O}_{2}}=32\]                    beacuse \[N{{H}_{3}}\]is lightest gas out of these gases                    \[\left[ r\propto \frac{1}{\sqrt{\text{Molecular}\,\text{Weight}}} \right]\]
