Predict whether the reaction
`2Ag_((s))+Zn_((aq))^(2+)rarr 2Ag_((aq))^(+)+Zn_((s))`
is feasible or not.

Explanation

The cell half reactions are
`{:("Anode",:,2Ag_((s))rarr2Ag_((aq))^(+)+2e^(-),E^(@)=0.80V),("Cathode",:,Zn_((aq))^(+)+2e^(-)rarrZn_((s)),E^(@)=-0.763V):}`
`E_("cell")^(@)=E_("cathode")^(@)-E_("anode")^(@)`
`E_("cell")^(@)=-0.763V-0.80V`
`=-.1563V`
Since `E_("cell")^(@)` is negative, the given reaction is not feasible.
