    Which pair of the gases diffuses with the same rate at same temperature and pressure?

    A)  \[CO\] and \[NO\]    

    B)  \[N{{O}_{2}}\] and \[C{{O}_{2}}\]

    C)  \[N{{H}_{3}}\] and \[P{{H}_{3}}\]  

    D)  \[NO\] and \[{{C}_{2}}{{H}_{6}}\]

    E)  \[C{{l}_{2}}\] and \[S{{O}_{2}}\]

    Correct Answer: D

    Solution :

                    Those gases which have same molecular weight, diffuses with the same rate at the same temperature and pressure, therefore NO and \[{{C}_{2}}{{H}_{6}}\] gases diffuse with the same rate because their molecular weights are same i.e., 30.
