Researchers are attempting to create a new battery based on the following chemistry and would like the battery to produce 1.0-1.2 volts. Given the standard cell potential of the reaction, they propose to connect 3 identical cells inside the single new battery. Calculate the voltage of this (3-cell) battery at 25oC when 1.3 M Fe2+ and 0.010 M Fe3+ in pH 4.1 buffer react with O2 at 0.20 atm. 4 Fe2+(aq) + O2(g) + 4 H+(aq) ⟶ 4 Fe3+(aq) + 2H2O(l) Eocell=0.46 volts
