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 25 C when 1.3 M Fe and 0.010 M Fe in pH 3.1 buffer react with O at 0.20 atm. (For full credit your answer must be correct to /-0.02.)
