Diazonium salt decompose as : C(6)H(5)N(...

Diazonium salt decompose as : `C_(6)H_(5)N_(2)CI^(-)rarrC_(6)H_(5)CI+N_(2)` At `0^(@) C` the evolution of `N_(2)` becomes two times faster when the initial concentration of the salt is doubled. Thus, it is

A

A first order reaction

B

A second order reaction

C

Independent of the intial concentration of reactant

D

A zero order reaction

Text Solution

Verified by Experts

The correct Answer is:
A
`r_(1)=k["salt"]^(n), r_(2)=2r_(1)=k[2 "salt"]^(n)`
`(2r_(1))/(r_(1))=(2)^(n),(2)^(1)=(2)^(n)n=1`
