We’re being asked to determine the equilibrium constant (K) at 298 K for the given reaction:
SO2(g) + 2 H2S(g) ⇋ 3 S(s) + 2H2O(g)
Step 1: Solve for ΔG˚rxn:
SO2(g) + 2H2S(g) ⇋ 3S (s) + 2H2O(g)
is the basis of a suggested method for removal of SO2, a pollutant that irritates airways causing coughing, from power-plant stack gases.
The values below may be helpful when answering questions about the process.
Calculate the equilibrium constant Kp for the reaction at a temperature of 298 K.
