During the electrolysis of a solution of copper sulfate on the cathode, m = 2.0 g of copper was released over a period of time at a current strength of I = 0.25 A. The distance between the rectangular electrodes is l = 30 cm, the area of each electrode is S = 50 cm2. Find the change in energy consumption required to obtain the same mass of copper at the same current strength if the distance between the electrodes is doubled and the immersion depth of the electrodes is 4 times. Specific resistance of the solution p = 0.33 Ohm • m, electrochemical equivalent of copper k = 3.3 • 10-7 kg/C.
