    A, B and C are ideal gases. Their molecular weights are 2, 4 and 28 respectively. The ran of diffusion of these gases follow the order

    A) \[C>A>B\]    

    B) \[~C>B>A\]

    C) \[A=B=C\]     

    D) \[~A>B>C\]        

    Correct Answer: D

    Solution :

     According to Graham's law of diffusion \[r\propto \frac{1}{\sqrt{M}}\] Hence, the order of rate of diffusion is Gases:               A > B > C Mol. weight:   2    4     28
