Aluminium oxide may be electrolysed at `1000^(@)`C to furnish aluminium metal (Atomic mass = 27 amu, 1 Faraday = 96500 Coulomb). The cathode reaction
Aluminium oxide may be electrolysed at `1000^(@)`C to furnish aluminium metal (Atomic mass = 27 amu, 1 Faraday = 96500 Coulomb). The cathode reaction is `Al^(3+) + 3e^(-) rightarrow Al`. To prepare 5.12 kg of aluminium metal by this method would require:
A. `5.49xx10^(1)C` of electricity
B. `5xx49xx10^(4)" Co of electricity"`
C. `1.83 xx10^(7) "C of electricity"`
D. `5.49xx10^(7) "C of electricity"`
