- B. controlling rate of reduction of the metal ions in a catalysis process, wherein the catalysis process comprises reacting the anode electrolyte comprising the metal ions in the higher oxidation state in the aqueous medium with an unsaturated or saturated hydrocarbon to form one or more organic compounds, the controlling step comprising:
- determining at least one first value for respectively at least one parameter, indicative of conditions of the catalysis process;
- comparing each of the at least one first value with respective at least one second value indicative of desired conditions of the catalysis process, wherein the at least one second value is in a predefined memory location;
