Redox Reactions

We are given that the cell potential , and we need to find the standard Gibbs free energy change ( ). The relation between the standard Gibbs free energy change and the cell potential is: where:
- is the number of electrons transferred in the reaction (which is 6 electrons based on the balanced equation),
- is the Faraday constant ( ),
- is the cell potential in volts.
Substituting the values: Thus, the standard Gibbs free energy change is .
