Question
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. (do not assume that this
is written as a spontaneous reaction, it may be written as an electrolytic cell).
3Hg2+(aq) + 2 Fe(s) → 6 Hg(1) + 2 Fe3+(aq)
Hg22+ (aq) + 2e → 2 Hg(1)
->
Fe3+(aq) +3 e → Fe(s)
E° = +0.80 V
E° = -0.04 V
1.52 V
-0.76 V
-0.84 V
0.84 V
