If `[Zn^(2+)]` is maintained at 1.0 M
(i) What is the minimum `(Cu^(2+))` for which the reaction
`Zn_((s))+Cu_((aq))^(2+) to Cu_((s))+Zn_((aq))^(2+)` is still spontaneous in forward direction.
(ii) Does the displacement of `Cu_((aq))^(2+)" by "Zn_((s))` go to completion?
`E_(Zn^(2+)//Zn)^(0)=-0.76V`
`E_(Cu^(2+)//Cu)=0.34V`
