Use standard reduction potentials to predict the electromotive force for the above reaction.
A) Calculate the standard reduction potentials for each half-reaction and then subtract the reduction potential of the anode from that of the cathode.
B) Use the Nernst equation to calculate the electromotive force for the given reaction.
C) Determine the number of electrons transferred in the reaction and use Faraday's constant to calculate the electromotive force.
D) None of the above.
