The rate constant for the $N_2H_4-Br_2$ reaction has been measured in sulfuric acid media by direct mixing method and chronopotentiometric method. The former gave 105 mole-1 l sec-1 whereas the latter 103 mole-1 l sec-1. It has been inferred that the former represents the rate constant for $N_2H_4-Br_2$ {\rightarrow} $N_2H_2$ and the latter for $N_2H_2+Br_2$ {\rightarrow} X. When the concentrations of KBr and $H_2SO_4$ are both high, drastic reduction of rate constant has been observed.
