Question 1

Which of the following statements concerning a lithium battery is false?
◦ A lithium battery is rechargeable.
◦ The cell reaction produces toxic mercury, so the batteries should be recycled.
◦ A lithium battery has a relatively high voltage, due in part to the high oxidation potential of lithium.
◦ It takes a small mass of lithium to provide one mole of electrons in the cell reaction.

Question 2

Shown below are the reactions occurring in the direct methanol fuel cell (DMFC).

I.	2 CH3OH(aq) + 2 H2O(l) → 2 CO2(g) +12 H+(aq) +12 e-

II.	3 O2(g) + 12 H+(aq) + 12 e- → 6 H2O(l)

Overall

2 CH3OH(aq) + 3 O2(g) → 2 CO2(g) + 4 H2O(l)

Which is the anode reaction, and what is being oxidized in the overall reaction?
◦ I, H2O
◦ II, O2
◦ I, CH3OH
◦ II, H+
