A cell, as shown below, consists of there compartments separated by porous pots. The first contains a cobalt eletrode in `5.0L` of `0.10M Co(NO_(3)),` the second contains `5.0L` of `0.10M KNO_(3),` the third contains an `Ag` electrode in `5.0L` of `0.10M AgNO_(3)`. Assuming that current with in the cell iis carried equally by the negative and positive ions by passign `0.1F` of electricity.

Given `: Co^(2+)+2e^(-) rarr Co" "E^(c-)=-0.28V`
Ag^(o+)+e^(-) rarr Ag" "E^(c-)=0.80V`
`2Ag^(o+)+Corarr Co^(2+)+2Ag" "E^(c-)._(cell)=1.08V`
The final concentration of `K^(o+)` in `I,II, `and `III` compartment is
A. `0.090,0.0,0.0100M`
B. `0.0,0.0100,0.090M`
C. `0.0,0.090,0.0100M`
D. `0.100,0.90,0.0M`
