A student wishes to determine the power output of an electrochemical cell that utilizes a half-reaction of copper oxide reducing to copper and a half-reaction of zinc oxidizing to zinc ions. The initial concentrations of the copper and zinc ions in the cell are 1.00 M and 0.10 M, respectively. The cell operates for 60 minutes at a constant rate of 0.200 A. Given that the standard cell potential is 1.10 V, calculate the power output of the electrochemical cell.
