Diazonium salt decomposes as
`C_(6)H_(5)N_(2)^(+)Cl^(-) rarr C_(6)H_(5)Cl + N_(2)`. At `0^(@)C`, the evolution of `N_(2)` becomes two times faster when the initial concentration of the salt is doubled. Therefore, it is

A

a first order reaction

B

a second order reaction

C

independent of the initial concentration of the salt.

D

a zero order reaction
