One of the many reactions which occur when iron ore is smelted in a blast furnace is given below. For this reaction, the equilibrium constant in terms of partial pressures, Kp, is 0.900 at 873 K and 0.396 at 1273 K. Assume the reaction takes place in a vessel containing only product and reactant molecules and that ΔH and ΔS do not change with temperature. FeO(s) + CO(g) ⇌ Fe(s) + CO2(g) a) Calculate ΔH, ΔG, and ΔS for the reaction at 873 K b) What is the mole fraction of CO2(g) at 873 K? c) Your equilibrium expression in a) and the mole fraction in b) should only include the gas phase species. Explain why, in no more than 2 sentences.
