Consider a modification to the Hall-Heroult process for aluminum production, where we keep things the same but replace the carbon electrode by something inert. The original process requires three electrons to produce one atom of Al metal and is: (1/2) Al½O3 + (3/4) C → Al + (3/4) CO2 Suppose that the new process also requires three electrons and is (1/2) Al,O; → Al + (3/4) O2 If the energy, E, produced from the reaction C + O2 → CO2 is 4.08 eV per carbon atom, how much would the voltage need to be increased in order produce aluminum assuming that the energy from the oxidation of carbon to carbon dioxide is replaced by electrical energy in the process?
