Abstract  

The kinetics of the oxidation of hydroxide ions by octacyanomolybdate(V) ions has been studied in the [OH] range between 0.5 and 4.0 mol dm−3. The reaction displays first-order kinetics in both [Mo(CN)8 3−] and [OH] and is consistent with the rate law R = k [Mo(CN)8 3−] [OH]. From the Brønsted-Bjerrum equation, it was established that the activated complex is formed by the ions Mo(CN)8 3− and OH. A reaction mechanism is proposed for the reaction with a rate constant of 1.13 ± 0.03 × 10−2 dm3 mol−1 s−1, activation enthalpy, ΔH#, of 20.1 ± 09 kJ mol−1 and activation entropy, ΔS*, of −213 ± 3 J K−1 mol−1.
