Kinetics of the Oxidation of Hydrazine by Hydrogen Peroxide,Catalyzed by Copper(II).

摘要

Hydrazine is oxidized by hydrogen peroxide in the presence of copper(II) to form nitrogen and water. The rate of reaction between stoichiometric amounts of hydrazine and hydrogen peroxide in the presence of copper(II) was followed by monitoring the rate of evolved nitrogen. The rate was first order with respect to concentrations of hydrogen peroxide and copper(II), but was independent of the concentration of hydrazine. The most likely mechanism involves formation of a copper(II) - hydrazine complex that reacts with the hydrogen peroxide. The enthalpy of activation and entropy of activation were found.
