On the basis of the information available from the reaction of ( mathrm{O}_{2} )
[
frac{4}{3} mathrm{Al}+mathrm{O}_{2} rightarrow frac{2}{3} mathrm{Al}_{2} mathrm{O}_{3}, Delta mathrm{G}=-827 mathrm{kJ} mathrm{mol}^{-1}
]
the minimum e.m.f. required to carry out electrolysis of ( mathrm{Al}_{2} mathrm{O}_{3} ) is ( left(mathrm{F}=96500 mathrm{Cmol}^{-1}right) )
(1) ( 2.14 mathrm{V} )
(2) ( 4.28 mathrm{V} )
(3) ( 6.42 mathrm{V} )
(4) ( 8.56 mathrm{V} )
