Question 1

Determine cell at 25 °C for the following reaction:

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

◦ 2.941 V
◦ -1.813 V
◦ 1.813 V
◦ -1.539 V
◦ 1.539 V

Question 2

Determine cell 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

◦ 0.212 V
◦ -0.462 V
◦ 0.462 V
◦ -0.212 V
◦ 0.424 V
