Decrease in free energy can be given by -ΔG = __________

A. nFE

B. n/FE

C. nF/E

D. F/nE

I have been asked this question during an internship interview.

I would like to ask this question from Fuel Cells topic in section Electro Chemical Cells and Corrosion of Applied Chemistry

Correct answer is A. nFE

To explain I would say: Decrease in free energy can be given by -ΔG = nFE where n= valency of ion, E = emf of cell and F=faraday.
