| Abstract: | The kinetics of the reactions of ClO3
− with HSO3
− and H2SO3 was studied by measuring the concentration of Cl−] and H+] both in chlorate-bisulfite and chlorate-sulfite/bisulfite solutions. A reaction mechanism was applied for simulation of
the experimental observations. Rate constants k1 = (1±0.5)·10−4 M−1 s−1 and k2 = (0.23±0.01) M−1 s−1 were determined for the following reactions:
|
((1)) |
|
((2)) |
Rate constant k1 was obtained directly from the experimental results of chloratesulfite/ bisulfite reactions, where reaction (1) is predominant.
Rate constant k2 was obtained by computer fitting of Cl−] and H+] to the experimental values both in chlorate-bisulfite and chlorate-sulfite/bisulfite reactions. |
