The emf of the cell reaction
`Zn(s) +Cu^(2+) (aq) rarr Zn^(2+) (aQ) +Cu(s)`
is `1.1V`. Calculate the free enegry change for the reaction. If the enthalpy of the reaction is `-216.7 kJ mol^(-1)`, calculate the entropy change for the reaction.

Explanation

To solve the problem step by step, we will calculate the free energy change (ΔG) and then the entropy change (ΔS) for the given cell reaction.

### Step 1: Calculate the Free Energy Change (ΔG)

The relationship between the standard free energy change (ΔG°), the number of moles of electrons transferred (N), Faraday's constant (F), and the electromotive force (E°) is given by the equation:

\[
\Delta G^\circ = -N \cdot F \cdot E^\circ
