An electrochemical cell is composed of pure nickel and pure iron electrodes immersed in solutions of their divalent ions. If the concentrations of Ni2+ and Fe2+ ions are 0.002 M and 0.40 M, respectively, what voltage is generated at 25(C? (The respective standard reduction potentials for Ni and Fe are -0.250 V and -0.440 V.)

(A) - 0.76 V

(B) - 0.26 V

(C) + 0.12 V

(D) + 0.76 V
