Calculate the standard cell potential (in V) given that the Gibbs free energy change is delta-G = -96.5 kJ/mol and the number of electrons transferred n = 1. (Faraday constant F = 96500 C/mol)

1. 1.0
2. 0.5
3. 2.0
4. -1.0

Correct answer: 1.0

Solution

delta-G = -nFE → E = -delta-G/(nF) = -(-96500 J/mol)/(1 x 96500 C/mol) = 1.0 V.
