APFIVE EMF from Gibbs Free Energy
A battery consists of two half-cells with different chemical potentials. If the redox reaction in the battery produces 2.0 electrons per reaction and the change in Gibbs free energy is -3.8×10^-19 J per reaction, what is the electromotive force (emf) of the battery?
A
2.4 V
B
1.2 V
C
3.8 V
D
0.6 V
