Question

Given the overall redox reaction:  Fe2+(aq) + Ce4+(aq) → Fe3+(aq) + Ce3+(aq)

Identify the two half-reactions

Oxidation half-reaction                            Reduction half-reaction

A) Fe2+(aq) → Fe3+(aq) + e                     Ce4+(aq) + e → Ce3+(aq)

B) Ce4+(aq) + e → Ce3+(aq)                    Fe2+(aq) → Fe3+(aq) + e

C) Fe2+(aq) + e → Fe3+(aq)                     Ce4+(aq) → Ce3+(aq) + e

D) Ce4+(aq) → Ce3+(aq) + e                    Fe2+(aq) + e → Fe3+(aq)

E) Fe3+(aq) →Fe2+(aq) + e                      Ce4+(aq) → Ce3+(aq) + e
