Consider the electrochemical cell with the following half-cell reactions: Fe3+ (aq) + e- → Fe2+ (aq) E° = +0.771 V and Cd2+ (aq) + 2e- → Cd (s) E° = -0.403 V What is the overall cell potential, Ecell, under standard conditions? Which species will be reduced at the cathode? Which electrode is the anode? Justify your choices using the given standard reduction potentials.
