    Diazonium salt decomposes as                 \[{{C}_{6}}{{H}_{5}}N_{2}^{+}C{{l}^{-}}\to {{C}_{6}}{{H}_{5}}Cl+{{N}_{2}}\] At \[{{0}^{o}}C\], the evolution of \[{{N}_{2}}\] becomes two times faster when the initial concentration of the salt is doubled. Therefore, it is               [MNR 1994; UPSEAT 2002]

    A)                 A first order reaction

    B)                 A second order reaction

    C)                 Independent of the initial concentration of the salt

    D)                 A zero order reaction

    Correct Answer: A

    Solution :

                    As doubling the initial conc. doubles the rate of reaction, order = 1.
