Popis:	Kinetics of the Mn(IV)→Mn(III) transition in the oxidation of watet to O2 was investigated at 60–100°C in 6–15 M H2SO4. The reaction is approximately 2-nd order in Mn(IV) concentration in the process of oxidation and 1-st order in initial Mn(IV) concentration. The kinetics is interpreted by the existence of dimeric forms Mn(IV)·Mn(IV), Mn(IV)·Mn(III) and Mn(III)·Mn(III). The suggested mechanism includes O2 formation directly in the coordination sphere of the Mn(IV)·Mn(IV) dimer in a polyelectronic process.
