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 `Co^(2+)` in `I, II, `and `III` compartment isA. `0.105,0.005,0.0M`B. `0.005,0.105,0.0M`C. `0.105,0.0,0.005M`D. 0.0,0.005,0.105M` |
