I am trying to generate activity-activity plots for the following reaction: Andalusite+Celadonite = Margarite + Muscovite I have calculated Thermodynamic data which includes the Log K for this reaction using SUPCRT92 (Johnson et al 1992). How do I incorporate this data within Act2 to generate a stability diagram that represents the activity of my reaction?? I have attached a sample of the type of diagram I need to plot. Please Help!!
