Chemistry - Electrochemistry Question with Solution | TestHub

On the basis of information available from the reaction $\frac{4}{3}\mathrm{Al}+{\mathrm{O}}_2\to \frac{2}{3}{\mathrm{Al}}_2{\mathrm{O}}_3,\Delta \mathrm{G}=-827\mathrm{kJ}{\mathrm{mol}}^{-1}$ of ${\mathrm{O}}_2$, the minimum e.m.f required to carry out an electrolysis of ${\mathrm{Al}}_2{\mathrm{O}}_3$ is $(\mathrm{F}=$ $96500\mathrm{C}{\mathrm{mol}}^{-1}):$NEET 2003
