S) a fuel cell produces electricity via a combustion reaction. a dmfc is a proton-exchange fuel cell that uses methanol ch3oh(l) as the fuel, which reacts with molecular oxygen to produce carbon dioxide and water.
(a) (4 pts) write the balanced combustion reaction for this methanol fuel cell.
(b) (4 pts) write the balanced half-reactions occurring at the cathode and anode of this fuel cell (assume standard acidic conditions).
(c) (4 pts) evaluate g (kj) and e (v) for the reaction in part (a) at 298 k.
(d) (4 pts) another possible product in the methanol fuel cell could be carbon monoxide. write the balanced reaction between methanol and oxygen gas to give only carbon monoxide and water.
(e) (4 pts) write the balanced half-reactions occurring at the cathode and anode of this fuel cell (assume standard acidic conditions). (f) (4 pts) evaluate g (kj) and e (v) for the reaction in part (d) at 298 k.
