Problem Details

Using the standard electrode potentials, determine the cell voltage for the following reaction when [Fe2+] = 0.10 M and [Cd2+] = 1.0 M.

Fe(s) + Cd2+(aq)  ⇌ Fe2+(aq) + Cd(s)

         Fe2+(aq) + 2 e -→ Fe(s)        E° = -0.44 V

         Cd2+(aq) + 2 e -→ Cd(s)        E° = -0.40 V

A. 0.04

B. 0.07

C. 0.01

D. 0.10

E. -0.02
