B We can now calculate Δ G ° using Equation 19.4.10 Because six electrons are transferred in the overall reaction, the value of n is 6: ΔGo = − nFEo cell = (6mol)(96, 468J / (V ⋅ mol))(0.14V) − 8.1 × 104J − 81 kJ / molCr2O7. Thus Δ G ° is −81 kJ for the reaction as written, and the reaction is spontaneous. Exercise.
