What is the value of AG° at 25.00 °C for the voltaic cell based on the following reaction 3Cd(s) + 2Rh3+(aq) 3Cd2+(aq) + 2Rh(s) The standard electrode potentials are: Rh3+ (aq) + 3e- Rh(s) E° = 0.76 V Cd2+(aq) + 2e Cd(s) E° = -0.40 V [Faraday constant: F = 96485 J/(V.mol)] -208 kJ/mol -672 kJ/mol -560. kJ/mol - 185 kJ/mol -34.7 kJ/mol
Free-energy change, AGº, is related to cell potential, Eº, by the equation AG° = -nFE° where n is the number of moles of electrons transferred and F = 96,500 C/(mol e ) is the Faraday constant. When Eº is measured in volts, AGⓇ must be in joules since 1 J =1C.V.
