An electrochemical cell is composed of pure nickel and pure iron electrodes immersed in solutions of their divalent ions at room temperature (25°C). 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.)
