Predict whether the following reaction (s) is (are) feasible or not
(i) `Fe+Zn^(2+)toFe^(2+)+Zn,E_(Zn)^(@)=-0.76,E_(Fe)^(@)=-0.44V`
(ii) `Zn+2Ag^(+)toZn^(2+)+2Ag,E_(Zn)^(@)=-0.76V,E_(Ag)^(@)=-0.80V`

Explanation

To determine whether the given reactions are feasible, we can use the standard electrode potentials (E°) of the half-reactions involved. A reaction is feasible if the cell potential (E° cell) is positive. The cell potential can be calculated using the formula:

\[ E°_{cell} = E°_{cathode} - E°_{anode} \]

Where:
- E°_{cathode} is the standard reduction potential of the species being reduced.
- E°_{anode} is the standard reduction potential of the species being oxidized.
