1.	You are given the following reduction reactions and E∘ values:Fe3+(aq)+e−→Fe2+(aq) E∘=+0.771 VFe2+(aq)+2e−→Fe(s) E∘=−0.447 VCalculate E∘ for the half-cell reaction Fe3+(aq)+3e−→Fe(s).
Answer» You are given the following reduction reactions and $E^{\circ}$ values: $F e^{3 +} (a q) + e^{-} \to F e^{2 +} (a q) E^{\circ} = + 0.771 V$ $F e^{2 +} (a q) + 2 e^{-} \to F e (s) E^{\circ} = - 0.447 V$ Calculate $E^{\circ}$ for the half-cell reaction $F e^{3 +} (a q) + 3 e^{-} \to F e (s)$ .
