A voltaic cell is made by placing an iron electrode in a compartment in which the Fe2+concentration is 2.0 × 10–5 M and by placing a Pt electrode in the other compartment, in which the H+ concentration is 3.50 M and PH2 = 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 25oC? A) 0.10 V B) 0.27 V C) 0.57 V D) 0.58 V E) 0.24 V
