Suppose 0.500 atm H2S, O2, H2O, and SO2 are added to a 1.000 L container at 25 degrees Celcius. Calculate the Delta G for this reaction under these conditions.
2H2S(g) + 3O2(g) <=> 2H2O(g) + 2SO2(g) Ka= 3.0X105
Calculate the delta S initial for the following raction at 410 K.
CO(g) + H20(g) => CO2(g) + H2(g) Delta H intial = -4.1 x 10^4 Delta S initial universe= 56 J/K
