Question 1

A common car battery consists of six identical cells, each of which carries out the reaction:
Pb + PbO2 + 2HSO4– + 2H+ 2PbSO4 + 2H2O
The value of E° for such a cell is 2.043 V. Calculate ΔG° at 25 °C for the reaction.

◦ –197.1 kJ
◦ –98.56 kJ
◦ –394.2 kJ
◦ –788.5 kJ
◦ –591.4 kJ

Question 2

A concentration cell is constructed using two metal (M) electrodes with M2+ concentrations of 0.10 M and 1.00 10–5M in the two half-cells. Determine the reduction potential of M2+ given that the potential of the cell at 25°C is 0.118 V.

◦ 0 V
◦ +0.118 V
◦ –0.118 V
◦ 0.237 V
◦ Cannot be determined with the information given.
