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.
