In a fuel cell hydrogen and oxygen react to produce electricity. In the process hydrogen gas is oxidised at the anode and oxygen at the cathode. If 67.2 litres of H_(2) at STP react in 15 minutes, what is the average current produced? If the entire current is used for electrodeposition of copper from Cu (II) solution, how many grams of copper will be deposited ? Anode reaction : H_(2) + 2OH^(-) rarr 2H_(2)O + 2e^(-) Cathode reaction : O_(2) + H_(2) O + 4e^(-) rarr 4OH^(-)
