Abstract: | Results on the oxidation of N by Br2 in neutral and acid media are presented. The rate of the reaction is found to be proportional to [N] and [Br2]. The gaseous product of oxidation is found to be pure nitrogen. The stoichiometry of the reaction is The reaction shows a positive salt effect. It is found that the addition of Br? stabilizes the complex BrN3, which decomposes into Br? and N2: The spectroscopic measurements also support the kinetic observation. The equilibrium constant K, the rate constants and the thermodynamic parameters were calculated. It is observed that H+ ion inhibits the reaction. The mechanism is discussed in terms of the kinetic results. |
