At 25°C, a student evaluates an electrochemical process for recovering zinc from an aqueous recycling stream. The reaction for the process is

\(\text{Zn}^{2+}\text{(aq)} + \text{Cu(s)} \rightarrow \text{Zn(s)} + \text{Cu}^{2+}\text{(aq)}\)

The standard cell potential for the reaction as written is \(-1.10\text{ V}\). Faraday's constant is \(96{,}500\text{ C/mol e}^-\). What is the standard Gibbs free-energy change, \(\Delta G^\circ\), for the reaction?
