Answer: The overall reaction for the electrolytic
Chapter 21, Problem 46P(choose chapter or problem)
The overall reaction for the electrolytic production of aluminum by means of the Hall process may be represented as
\(\mathrm{Al}_2\mathrm{O}_3(s)+3\mathrm{C}(s)\ \longrightarrow\ 2\mathrm{Al}(l)+3\mathrm{CO}(g)\)
At \(1000^{\circ} \mathrm{C}\), the standard free-energy change for this process is 594 kJ/mol. (a) Calculate the minimum voltage required to produce 1 mole of aluminum at this temperature. (b) If the actual voltage applied is exactly three times the ideal value, calculate the energy required to produce 1.00 kg of the metal.
