A rechargeable battery is constructed based on a concentration cell constructed of two Ag/Ag+ half-cells. The volume of each half-cell is 2.2 L and the concentrations of Ag+ in the half-cells are 1.25 M and 1.2×10−3 M .
At which half-cell does the concentration of Ag+ decrease as the cell is run? What is the initial concentration of Ag+ at that half-cell?
At which half-cell does the concentration of Ag+ decrease as the cell is run?
What is the initial concentration of Ag+ at that half-cell?
anode; 1.2×10−3 M
anode; 1.25 M
cathode; 1.25 M
cathode; 1.2×10−3 M
What is the concentration of Ag+ at the cathode after the cell is run at 3.3 A for 5.8 h ? What is the concentration of Ag+ at the cathode when the cell is "dead"? For how long can this battery deliver 2.5 A of current before it goes dead? |
