Question

Which of the following relations is correct for free energy change and cell potential?
(A) ΔG = nFEcell
(B) ΔG = - n/F Ecell
(C) ΔG = - nFEcell
(D) ΔG = nF/Ecell

Answer 1

Answer:

D is the correct answer

Answer 2

Answer:

(C) ΔG = - nFEcell

Explanation:

Since we know that the electrochemical reaction is the reaction which is associated with a decrease in Gibbs free energy.

Gibs free energy is also known as free enthalpy of the reaction.

Option (C) is the correct option.

ΔG = - nFEcell

Here ΔG is changing in free Gibbs energy.

n= No.of free electrons, F=Faraday, E cell=Potential of the cell.
