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 25oC?
A) 0.10 V
B) 0.57 V
C) 0.27 V
D) 0.25 V
E) 0.56 V
