Sulfite liquid phase, rate equation

Measurements Using Liquid-Phase Reactions. Liquid-phase reactions, and the oxidation of sodium sulfite to sodium sulfate in particular, are sometimes used to determine kiAi. As for the transient method, the system is batch with respect to the liquid phase. Pure oxygen is sparged into the vessel. A pseudo-steady-state results. There is no gas outlet, and the inlet flow rate is adjusted so that the vessel pressure remains constant. Under these circumstances, the inlet flow rate equals the mass transfer rate. Equations (11.5) and (11.12) are combined to give a particularly simple result ... 

Oxygen dissolves into and reacts irreversibly with aqueous sodium sulfite solutions. If the gas solubility is denoted as at the liquid-gas interface, derive the elementary differential equation that describes the steady-state composition profile of oxygen in the liquid phase when the rate of oxygen reaction is represented by. 4and the local...
