(a) Calculate the standard free energy change and maximum work obtainable for the reaction. `Zn(s)+Cu^(2+)(aq)hArrCu(s)+Zn^(2+)(aq)`
[Given `E_(Zn^(2+)//Zn)^(@)=-0.76V,E_(Cu^(2+)//Cu)^(@)=+0.34V,F=96500" C "mol^(-1)`]
(b) also calculate the equilibrium constant for the reaction.

Explanation

To solve the given problem, we will break it down into two parts:

### Part (a): Calculate the standard free energy change (ΔG°) and maximum work obtainable for the reaction.

1. **Identify the half-reactions and their standard reduction potentials**:
- For the reduction of copper:
\[
\text{Cu}^{2+} + 2e^- \rightarrow \text{Cu}(s) \quad E^\circ = +0.34 \, \text{V}
