For the cell (at 298K)
`Ag(s) | AgCl(s) | Cl^(-)(aq)|| AgNO_(3)(aq) | Ag(s)`
Which of the following is correct?
A. The cell emf will be zero when `[Ag^(+)]_(a)` = `[Ag^(+)]_(c)` ([Ag^(+)] in anodic compartment = `[Ag^(+)]` in cathodic compartment).
B. The amount of AgCl(s). Precipitate in anodic compartment will decrease with the working of the cell.
C. The concentration of `[Ag^(+)]` = constant, in anodic compartment during working of cell .
D. `E_(cell) = E_(Ag^(+)|Ag)^(@) - (0.059/1)log (1/[Cl^(-)]_(a))`
