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. WebNernst equation. In electrochemistry, the Nernst equation is a chemical thermodynamical relationship that permits the calculation of the reduction potential of a reaction ( half-cell or full cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the redox reaction, and activities (often ...
