31. A fuel cell uses H:(8) and O_() to form H,0. The half cell reactions are given below. The standard electrode em for the cell 1.23 V. The maximum electrical work per mole of H,0 from the cell is: (F=96,500) (A) 119 Cathode: 4e +O_(8) + 2 H2O(1) 40H (aq) (B) 237 kJ Anode: 2 H.(8) + 4OH(aq) 41,0 + 4e (C) 475 kJ Cell: 2 H (8) + (g) 2 H 0() (D) 1.23)
