# Diazonium salt decomposes as $C_6H_5N^{+}_2CL^{-} \longrightarrow C_6H_5Cl+N_2$

$(A)\;\text{a first order reaction } \\ (B)\;\text{a second order reaction } \\(C)\;\text{independent of the initial concentration of the salt } \\(D)\;\text{a zero order reaction }$

Since on increasing the concentration of salt by two times evolution of $N_2$ also increases that it is clear that the rate $\alpha$ concentration .
