Witryna1 lut 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. WitrynaThe same line of reasoning gives the same value for I2 Fourth, calculate the equilibrium concentrations using initial and change values. the equilibrium concentration is the initial minus that consumed.
