    The following data are for the decomposition of ammonium nitrate in aqueous solution                 Volume of \[{{N}_{2}}\] in cc                       Time (minutes)                                 6.25                        10                                 9.50                        15                                 11.42                     20                                 13.65                     25                                 35.05         Finally                 The order of the reaction is                                         [NCERT 1980]

    A)                 Zero      

    B)                 One

    C)                 Two      

    D)                 Three

    Correct Answer: B

    Solution :

                    \[K=\frac{2.303}{t}\log \frac{{{V}_{\infty }}}{{{V}_{\infty }}-{{V}_{t}}}\] gives constant value of K.  With the given date.  Hence it is 1st order.
