A Voltaic Cell Is Made by Placing an Iron Electrode

Multiple Choice

A voltaic cell is made by placing an iron electrode in a compartment in which the Fe²⁺ concentration is 3.0 × 10^-5 M and by placing a Pt electrode in the other compartment,in which the H⁺ concentration is 3.10 M and = 1.00 atm.The Fe²⁺/Fe half-cell reduction potential is -0.41 V,and the H⁺/H₂ half-cell reduction potential is 0.00 V.What is E for the cell at 25^oC?

A) 0.10 V
B) 0.57 V
C) 0.27 V
D) 0.25 V
E) 0.56 V
