Question 1

Determine Keq at 25 °C for the following reaction:
Pb2+(aq) + Cu(s) Cu2+(aq) + Pb(s)

The half-reactions are:
Pb2+(aq) + 2 e- Pb(s) = -0.125 V
Cu2+(aq) + 2 e- Cu(s) = +0.337 V

◦ 2 × 1069
◦ 3 × 10-16
◦ 2 × 1016
◦ 2 × 10-8
◦ 6 × 107

Question 2

Determine the Ksp at 25 °C of AgCl(s). The half-reactions are:

Ag+(aq) + 1 e-→ Ag(s) = +0.771 V
AgCl(s) + 1 e-→ Ag(s) + Cl-(aq) = +0.222 V

◦ 1 × 10-2
◦ 0.771
◦ 4 × 1011
◦ 5 × 10-10
◦ 4 × 10-11
