We are given with a redox reaction described by the kinetics and the electrode potential of the anode half cell and cathode half cell. The electrode potential of the cell is the difference between the electrode potential of the cathode and the electrode potential of the anode. The equation is E cell = 1.587 V - 0.536 V equal to 1.051 V. Answer is B.
