The reaction SO2(g) + 2H2S(g) ⇌ 2S(s) + 2H2O(g){“version”:”1.1″,”math”:”SO2(g) + 2H2S(g) ⇌ 2S(s) + 2H2O(g)”} is the basis of a suggested method for removal of SO2 from power-plant stack gases. a. What is the equilibrium constant for the reaction at 298 K? (4 marks) b. In principle, is this reaction a feasible method for removing SO2? (2 marks) c. If initially PSO2 = PH2S and the vapor pressure of water is 25 torr, calculate the equilibrium SO2 pressure in the system at 298 K. (2 marks) d. Would you expect the process to be more or less effective at higher temperatures? Explain. (2 marks)
