The annual production of cl2 is about 45 million tons per year. assume that a typical plant is operational 90% of the year. the operating voltage of a cell is 3.4 v (considerably higher than the equilibrium voltage). (a) write down the half-cell reaction for the oxidation chloride to form chlorine. (b) determine the total current worldwide needed to gener- ate the global supply of cl2. (c) calculate the electrical power needed to produce the global supply of chlorine using electrolysis.
