Sulfur dioxide is a significant air pollutant, especially from coal-fired power-plants. The following reaction is the basis of a suggested method for removal of SO, from power-plant exhaust gases. Is this reaction a feasible method of removing SO,? Why or why not? Support your answer using the provided thermodynamic data. SO2(s) + 2H2S(g) → 3S(s) + 2H,O (g) AG° = -90.5 kJ AH° = -146 kJ AS° = -186 J/K

Is this reaction a feasible method of removing SO2? Why or why not?
Sulfur dioxide is a significant air pollutant, especially from coal-fired power-plants.
The following reaction is the basis of a suggested method for removal of SO, from
power-plant exhaust gases. Is this reaction a feasible method of removing SO,? Why
or why not? Support your answer using the provided thermodynamic data.
SO2(g) + 2H2S(g) → 35(s) + 2H2O (g)
AG° = -90.5 kJ
AH° = -146 kJ
AS° = -186 J/K
