An electrolytic cell is constructed using platinum electrodes in an aqueous NaHCO3 solution. The electrolytic cell is attached to a 9V battery for 2.5 hours, producing 55 mL of H₂(g) at 1.00 atm and 298 K. 2HCO3(aq) + 2e → H₂(g) + 2CO32-(aq) E° = -0.83 V O2(g) + 4CO2(g) + 2H2O(l) + 4e → 4HCO3- (aq) E° = 2.73 V a. Identify the anode reaction, cathode reaction, and cell reaction. Anode: Cathode: Cell: b. Calculate the current running through the cell.
