Problem Details

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°C.

3 Cl2(g) + 2 Fe(s) 6 Cl  (aq) + 2 Fe3+(aq)

Cl2(g) + 2 e       →      2 Cl  (aq)                                        E° = +1.36 V

Fe3+(aq) + 3 e–      →         Fe(s)                                         E° = -0.04 V

A) +4.16 V

B) -1.40 V

C) -1.32 V

D) +1.32 V

E) +1.40 V
