Given $: E^{o}_{Fe^{3+}/Fe}=-0.036V, E^{o}_{Fe^{2+}/Fe}=-0.439V$. The value of standard electrode potential for the change, $Fe^{3+}_{\left(aq\right)}+e^{-} \rightarrow Fe^{2+}\left(aq\right)$ will be :

The cell, $Zn\left|Zn^{2+}\left(1M\right)\right|\left|Cu^{2+}\left(1M\right)\right|Cu\left(E^{0}_{cell}=1.10V\right), $ was allowed to be completely discharged at $298 \,K$. The relative concentration of $Zn^{2+} to Cu^{2+}\left[\frac{\left[Zn^{2+}\right]}{\left[Cu^{2+}\right]}\right]$ is

Aluminium oxide may be electrolysed at 1000 $^{\circ}$C to furnish aluminium metal (Atomic mass = 27 amu: 1 faraday = 96,500 Coulombs). The cathode reaction is $Al^{3+} + 3e^- \to Al^{\circ}$ To prepare 5.12 kg of aluminium metal by this method would require :
