    For an elementary reaction, 2A + B\[\to \]C + D the molecularity is                                           [Kurukshetra CEE 2002]

    A)                 Zero      

    B)                 One

    C)                 Two      

    D)                 Three

    Correct Answer: D

    Solution :

               \[2A+B\to C+B\]                      Rate = \[k{{[A]}^{2}}{{[B]}^{1}}\]                    \[\therefore O.R.=2+1=3\] and molecularity is \[3[2A+B]\].
