In this equation, what does n represent?
e0 = -δg/nf
a) number of electrons in the cell
b) number of electrons in the reactants
c) number of moles of electrons transferred
d) number of products in the equation
e) number of reactants in the quotient

Option (C) is the correct answer.

Explanation:

An equation which relates the reduction potential of an electrochemical reaction with the standard electrode potential, temperature or concentration of chemical species undergoing the chemical reaction.

Mathematically,    

where         = Gibb's energy

                            n = number of electrons transferred

                            F = Faraday's constant

                            E = electrochemical potential

Thus, we can conclude that in the equation E0 = -ΔG/nF, 'n' represents number of moles of electrons transferred.
