TLDR
The kinetic data of the reaction were calculated from the absorption rate of oxygen into the mechanically agitated sulphite solutions and it was found that the reaction order in oxygen depends on the oxygen concentration in the liquid phase at the interface.About:

The oxidation of aqueous sodium sulphite solutions
K.J.A. de Waal,J.C. Okeson +1 more
TL;DR: In this article, a method for the determination of the interfacial area between a gas and a liquid and of the surface renewal rate of this interface was proposed based on the oxidation of a concentrated aqueous sulphite solution with gaseous oxygen in the presence of cobaltous sulphate as a catalyst.
