Depict the progress of the reaction graphically (as in Fig. 5G.1) for the reaction in Exercise 5G.13 if the starting partial pressures of I2 and I are 0.75 bar and 0.12 bar, respectively.

Exercise 5G.13

(a) Calculate the reaction Gibbs free energy of I₂ (g) → 2 I (g) at 1200. K (K = 6.8) when the partial pressures of I₂ and I are 0.13 bar and 0.98 bar, respectively.

(b) Indicate whether this reaction mixture is likely to form reactants, is likely to form products, or is at equilibrium.
