Lead storage batteries are rated by ampere-hours, that is, the number of amperes they can deliver in an hour. (a) Show that 1 Ah = 3600 C. (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 electrode reactions on page 828.) (c) Calculate E°cell and ΔG° for the battery.
