Study of Hydrazine-Bromine Reaction in Sulfuric Acid Media

[摘要] The rate constant for the N2H4-Br2 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 N2H4 + Br2 ¡æ N2H2 and the latter for N2H2 + Br2 ¡æ X. When the concentrations of KBr and H2SO4 are both high, drastic reduction of rate constant has been observed.
