A zinc electrode is connected to a copper electrode by a wire in a beaker that has a solution of 0.1 M CuSO4 and 0.1 M ZnSO4. The initial reduction potential of the copper electrode is +0.34 V, and the initial oxidation potential of zinc is –0.76 V. What is the potential difference between the two electrodes at 298 K, and what is the rate of the electrochemical reaction when the cell operates at a current of 2.50 A?
