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

Answer»

a FIRST order REACTION
a second order reaction
independent of the initial concentration of the salt
a zero order reaction

Solution :As doubling the initial CONC. Doubles the RATE of reaction, order=1
