a) Lead-acid batteries can deliver, for a few seconds, huge surge currents, a useful i car and truck engine ignition. For a lead-acid battery providing a 400 ampere surge cuncim (400 Coulombs per second), use the cell reaction PbO2(s) + Pb(s) + 2 H (aq) + 2 HSO4-(aq) - 2 PbSO4 (s) +2 H2O(1) to calculate the number of moles of PbO2 and Pb that react per second. D) Write the Nernst equation for the lead-acid battery, (Assume ideal-solution behavior.) c) Use the Nernst equation to show the voltage of a lead-acid battery drops as the battery is discharged.
