Question 1

Suppose the reaction Pb(s) + 2H+(aq) → Pb2+(aq) + H2(g) is carried out at pH = 4.00 and at a hydrogen gas pressure of 1.00 atm.  The concentration of lead(II) ions that causes this reaction to be at equilibrium is
◦ 2.5 M
◦ 1.6 × 10–2 M
◦ 2.5 × 10–4 M
◦ 1.6 × 10–6 M
◦ 0.40 M

Question 2

The half-cell reaction for the oxidation of H2O(l) to O2(g) is given below.
         2H2O(l) → O2(g) + 4H+(aq) + 4e–
Which choice lists all of the following species that can oxidize H2O to O2(g) under standard-state conditions?
         MnO4–(aq), Cl2(g), Pb2+(aq), Cl– (aq), Ag+(aq)
◦ Cl–(aq) only
◦ Cl2(g) only
◦ Pb2+(aq) and Ag+(aq)
◦ Cl–(aq) and MnO4–(aq)
◦ MnO4–(aq) and Cl2(g)
