Conclusions
-
1.
Using the temperature-jump method, the authors have investigated chemical relaxation in aqueous bromide solutions containing chloride and bromide ions.
-
2.
The reaction of BrCl with a water molecule is far more rapid than the analogous reaction between bromine and water molecules.
-
3.
The rate constant of the reaction Br2OH- + H+ ⇌ Br2 + H2O is close to the diffusion limit of the rate constant of a bimolecular reaction in a solution.
-
4.
The rate constant of the reaction BrClOH- +H+ ⇌ BrCl + H2O is much lower than the values of the diffusion limit, indicating the presence of a small free-energy barrier in this proton transfer process.
