Problem
Acid rain occurs by dissolution of SO3 in aqueous droplets. SO2 from coal burning power plants is the culprit. The reaction is SO2(g) + 0.5O2(g) → SO3 (g). What is the equilibrium constant for this reaction at 298 K? If the partial pressure of O2 is 0.21 atm, what is the equilibrium ratio of partial pressures of SO3 to SO2 at 298 K?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
