General Questions
These questions are not explicitly keyed to chapter topics; many require integration of several concepts.
A 12-V automobile battery consists of six cells of the type described in Section 19.9. The cells are connected in series so that the same current flows through all of them. Calculate the theoretical minimum electrical potential difference needed to recharge an automobile battery. (Assume standard-state concentrations.) How does this compare with the maximum voltage that could be delivered by the battery? Assuming that the lead plates in an automobile battery each weigh 2.50 kg and that sufficient PbO2 is available, what is the maximum possible work that could be obtained from the battery?
