Chapter 19, Problem 117AP

Lead storage batteries are rated by ampere-hours, that is. the number of amperes they can deliver in an hour. (a) Show that $\text{1 Ah = 3600 C}\text{.}$ (b) The lead anodes of a certain lead-storage battery have a total mass of 406 g. Calculate the maximum theoretical capacity of the battery in ampere-hours. Explain why in practice we can never extract this much energy from the battery. (Hint: Assume all the lead will be used up in the electrochemical reaction, and refer to the lead storage-battery electrode reactions in Section 19.6.) (c) Calculate $E{°}_{\text{cell}}\text{ and }\Delta G\text{ for}$ the battery.
