Reduction and oxidation must occur together. The electrons from the oxidized species are transferred to the reduced species. Chemists often break these two processes apart and write what are referred to as "half reactions." Consider these two half reactions: Zn2+ (aq) + 2 e- → Zn (s) Cu2+ (aq) + 2 e- à Cu (s) a. Are these oxidation or reduction half reactions? b. Calculate ΔG° for each of these reactions. Note that ΔG°f for the electron is 0 kJ/mol. c. Based on your answer to (b), does Zn2+ or Cu2+ more strongly favor reduction?
