Question 1

Determine cell for the reaction: Pb2+(aq) + Zn(s) → Pb(s) + Zn2+(aq). The half reactions are:

Pb2+(aq) + 2 e-→ Pb(s) = -0.125 V
Zn2+(aq) + 2 e-→ Zn(s) = -0.763 V

◦ 0.638 V
◦ -0.638 V
◦ 0.888 V
◦ -1.276 V
◦ -0.888 V

Question 2

Determine Ecell at 25 °C for the following reaction at 25 °C:

Al(s) Al3+(0.435 M) Sn2+(2.12 × 10-3 M) Sn(s)
3 Sn2+(aq) + 2 Al(s) → 2 Al3+(aq) + 3 Sn(s)
Al3+(aq) + 3 e-→ Al(s) = -1.676 V
Sn2+(aq) + 2 e-→ Sn(s) = -0.137 V

◦ 1.227 V
◦ 1.611 V
◦ 1.562 V
◦ 1.487 V
◦ 1.467 V
