The reaction of calcium oxide with the pollutant, sulfur trioxide, to produce calcium sulfate has been proposed as one way to remove the the SO3 from the smoke resulting from burning high sulfur coal (as in a power plant). Using the values from appendix C in the text Calculate the Standard free energy change for the reaction at 298K.
CaO = (-635.1) all in KJ/molSO3 = (-395.7)CaSO4 = (-1434)
