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 L of H2 at STP react in 15 min, what is the average current produced? If the entire current is used for electro-deposition of copper from copper (II) solution, how many grams of copper will be deposited?
Anode reaction : H2 + 2OH- → 2H2O + 2e-
Cathode reaction : O2 + 2H2O + 2e- → 4OH-
