Construct a pe-pH diagram for the following species of sulfur: HSO4,SO42,H2S,HS, and S2 at 25C and 0.1MPa. The following free energies of formation should provide sufficient information to complete this task. Values are in kJ/mole, standard state is 25C and 0.1MPa.R=8.314J/moleK. What I would like to know, specifically, is how to get the pe and pH values, in extensive detail. I would also like to know how the pee-pH diagram should look like. I know how to get up to the log K values. How do I use them, to get the pe and pH values that I will plot
