In an car battery recharging occurs when the car is running by supplying a current to the battery. The reaction that occurs at the cathode in this electrolytic process is   Pb2+  + 2e- -->  Pb (s) If the car supplies a current of 1.50A to the battery, how long will it take in minutes to have 25.0 g of Pb(s) collected at the cathode? Hint: Start with 25.0 g Pb (1A = 1C/sec)  (F= 96500 C/mole e-)  (Pb =207.2g/mol) Answer has 3 sig figs
