Question

A voltaic cell is made by placing an iron electrode in a compartment in which the concentration is 2.0 x10-5M and by placing a Pt electrode in the other compartment, in which the H+concentration is 3.4 M and PH2= 1.00 atm. The /Fe half-cell reduction potential is -0.41 V, and the H+/H2 half-cell reduction potential is 0.00 V. What is the equilibrium constant at 25ºC for the spontaneous cell reaction?
A) 4 x104
B) 5 x1020
C) 5 x1022
D)
E)
