WebKelvin, n is the number of electrons transferred in the balanced equation, F is the Faraday constant (96,485 C/mol), and Q is the reaction quotient. At equilibrium, Q is equal to the equilibrium constant (Kc). At 298 K: Ecell = E cell - (RT/nF)In(Kc) Solving for Kc, we get: Kc = exp((E cell - Ecell)/(RT/nF)) Substituting the values, we get: WebYou then multiply by ln (10) to have E° instead of E°/ln (10) and you find : E° = (b * ln10/n)log (K). He calculated b*ln10 and found 0.0592V. In the end, your equation is this : E° = (0.0592/n)log (K) When you use the equation G=-RTlnK, you …
