Aluminum metal is produced by passing an electric current through bauxite, which contains Al₂O₃ dissolved in the molten mineral cryolite. Graphite rods serve as electrodes, and we can write the redox equation as follows:

Indicate each of the following for this nonspontaneous process:

(a) Oxidation half-cell reaction

(b) Reduction half-cell reaction

(c) Anode and cathode

(d) Direction of electron flow.
