To find the `K_(sp)` of `AgBrO_(3)`, a student prepared one litre of a saturated solution by adding only sufficient `AgBrO_(3)` in water at `27^(@)C`. He found that a copper wire left in the solution overnight become covered with silver and `Cu^(2+)` ion were also formed in the solution. The wire was dried and found to weigh 15.25 mg more that its original weight. `Cu(s)+2Ag^(+)(aq)hArrCu^(2+)(aq)+2Ag(s)`,
`DeltaG^(@)=-110.4kJ`
[Given: `R=8J//K-"mol",Cu=63.5,Ag=108`]
The `K_(sp)` for `AgBrO_(3)` is:

A

`1.0xx10^(-46)`

B

`1.0xx10^(46)`

C

`2.0xx10^(-4)`

D

`4.0xx10^(-8)`
