CQXA · **on:** Feb 15, 2020

Question 1

Shown below are the reactions occurring in the proton-exchange membrane (PEM) fuel cell.

I.	2 H2(g) → 4 H+(aq) + 4 e-

II.	O2(g) + 4 H+(aq) + 4 e- → 2 H2O(l)

Overall

2 H2(g) + O2(g) → 2 H2O(l)

Which is the cathode reaction, and what is being oxidized in the overall reaction?
◦ I, O2
◦ II, O2
◦ I, H2
◦ II, H2

Question 2

Which of the following statements concerning the rusting of iron is false?
◦ Salt increases the rate of corrosion by providing ions to carry the current.
◦ The oxidation site can occur at a different place on the metal surface than the reduction site.
◦ The rusting of iron requires both oxygen and water.
◦ The metal is reduced.
