The annual production of Cl2 is about 45 millions 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). Required:
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.
