Write equations for the reactions taking place at the two electrodes (mentioning clearly the name of the electrode) during the electrolysis of:
Molten lead bromide with inert electrodes.

Explanation

`PbBr_2 harr Pb^(2+) + 2Br^(-)`
Cathode : `Pb^(2+) + 2e^(-) rarr Pb` (Reduction)
Anode: `2Br^(-) - 2e^(-) rarr Br_2` (Oxidation)
