A rechargeable battery is constructed based on a concentration cell constructed of two Ag/Ag+ half-cells. The volume of each half-cell is 2.1 L and the concentrations of Ag+ in the half-cells are 1.30 M and 1.2×10−3 M . Part A For how long can this battery deliver 2.8 A of current before it goes dead? Part B What mass of silver is plated onto the cathode by running at 3.7 A for 5.3 h ? Part C Upon recharging, how long would it take to redissolve 100 g of silver at a charging current of 10.0 amps?
