    The mean free path of collision of gas molecules varies with its diameter  of the molecules as

    A)  \[d{{-}^{1}}\]              

    B)  \[d{{-}^{2}}\]

    C)  \[d{{-}^{3}}\]

    D)  \[d{{-}^{4}}\]

    Correct Answer: B

    Solution :

    Mean free path of gas molecules \[\lambda =\frac{{{\lambda }_{1}}+{{\lambda }_{2}}+.....{{\lambda }_{1}}}{n}\] \[\lambda =\frac{1}{\sqrt{2}\pi n{{d}^{2}}}\] \[\lambda \propto {{d}^{-2}}\]
