Express the equilibrium constant K, through the molecular partition functions, and the difference between the molar dissociation energies for all products and all reactants. (2 marks) In parts (c)- (g), analyze the equilibrium constant Ke contributions for T = 300 K. (c) The dissociation energies Do are 432.1 kJ mol-¹ for H₂, 148.8 kJ mol-¹ for 1₂. and 294.7 kJ mol-¹ for HI. What is the contribution to K, from AD? (4 marks) (d) Assume that m1 amu, and m-127 amu. What is the translational contribution to Ko? (4 marks) (e) Assume that t= 85.3 K for H₂, et = 0.0537 K for 1₂, and got = 9.25 K for HI. What is the rotational contribution to K.? (4 marks) (f) Assume that the fundamental vibrational frequency = 4260 cm¹ for H₂, v= 250 cm¹ for 12, and v= 2324 cm¹ for HI. What is the vibrational contribution to Ke? (4 marks) (g) What assumption can be made about the electronic contribution to the equilibrium constant, and why? (2 marks)
