WebFeb 1, 2024 · E° cell = E° ox + E° red. E° cell = -0.20 V + 1.33 V. E° cell = +1.13 V. Step 3: Find the equilibrium constant, K. When a reaction is at equilibrium, the change in free energy is equal to zero. The change in free energy of an electrochemical cell is related to the cell potential of the equation: ΔG = -nFE cell. where. WebNov 1, 2008 · E = Eo- RT/nF lnQ This will be rearranged to make lnQthe subject. The first step in doing this is to subtract Eofrom each side to give E - Eo= Eo- RT/nF lnQ - Eo which simplifies to E - Eo = - RT/nF lnQ Both sides can now be multiplied by -1 to give -(E- Eo) = - (-RT/nF lnQ) or Eo- E = RT/nF lnQ
