Diazonium salt decomposes as
C6H5N2+Cl−→C6H5Cl+N2
At 0∘C , the evolution of N2 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
