The reaction
SO2(g) + 2 H2S(g) ⇌ 3 S(s) + 2 H2O(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? (b) In principle,
is this reaction a feasible method of removing SO2?
(c) If PSO2 = PH2S and the vapor pressure of water is 25 torr,
calculate the equilibrium SO2 pressure in the system at
298 K. (d) Would you expect the process to be more or
less effective at higher temperatures?
