    The following data are for the decomposition of ammonium nitrite in aqueous solution
    Vol. of N2 in cc Time (min.)
    6.25 10
    9.00 15
    11.40 20
    13.65 25
    35.65 \[\infty \]
    The order of reaction is

    A) zero                                      

    B)        one

    C)        two                                       

    D)        three

    Correct Answer: B

    Solution :

    For first order reaction                  \[k=\frac{2.303}{t}\log \frac{a}{a-x}\]                 \[a\propto {{V}_{\infty }}(=35.05)\]and\[x\propto {{V}_{t}}\] constant values of k calculated for different times shows first order reaction.
