A student wants to calculate the efficiency of an electrochemical cell with a standard potential of -0.74 volts. The cell is set up with a copper electrode immersed in a solution of copper(II) sulfate and a silver electrode immersed in a solution of silver nitrate, connected by a salt bridge. The student measures a current of 0.5 amperes flowing through the cell for a duration of 60 minutes. Calculate the efficiency of the electrochemical cell in terms of the amount of reactants consumed and the amount of product formed.
