Calculate the standard cell potential of an electrolytic cell when given the following half reactions.
Standard Reduction Potentials
Fe3+ (aq) + e – → Fe2+ (aq) E°red = + 0.769 V
Li+ (aq) + e – → Li (s) E°red = – 3.04 V
What is E° (cell) for the reaction 2 Au(s) + 3 Ca2+(aq) → 2 Au3+(aq) + 3 Ca(s)?
