Diazonium salt decomposes as C(6)H(5)N...

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 initial concentration of reactant

D

a zero order reaction

Text Solution

Verified by Experts

The correct Answer is:
A
For a first order reaction
r =k[A]
Hence when conc. of `(C_(6)H_(5)N_(2)^(+)Cl^(-))` is doubled the conc. of nitrogen gets doubled.
