Q2 (35%). The hot molten mixture of alumina with cryolite is electrolyzed in a Hall-Heroult Cell at a low voltage of 5 volts and a high current of 50kA. Aluminum metal is produced at the cathode at a production rate of 365kg per day. The thermodynamic cell potential is E=1.12 volts. Molar mass of aluminum is 27g/mol. Calculate: 1) Current efficiency 2) Specific energy consumption in MJ/kg 3) Energy efficiency
