When zinc is refined by electrolysis, the desired half-reaction at the cathode is A competing reaction, which lowers the yield, is the formation of hydrogen gas: If 85.6% of the current flowing results in zinc being deposited, while (100-85.6)% produces hydrogen gas, how many liters of H2, measured at STP (hydrogen gas occupies 22.4 L/mol), form per kilogram of zinc
