WebAug 15, 2024 · The Nernst Equation is derived from the Gibbs free energy under standard conditions. (1) E o = E r e d u c t i o n o − E o x i d a t i o n o. Δ G is also related to E … WebΔG = ΔG ∘ + RTlnQ. Notice the reaction quotient, Q, appears in this equation, making the free energy change dependent upon the composition of the reaction mixture. Substituting the equation relating free energy change to cell potential yields the Nernst equation: − nFEcell = − nFE ∘ cell + RTlnQ Ecell = E ∘ cell − RT nFlnQ. sb 731 how to petition
