thais98 Posted December 21, 2020 Share Posted December 21, 2020 Hello! My knowledge of geochemistry is kinda poor and I've recently started using the GWB software with the Professional Demo. I need to run some reactions to see the amount of calcite that precipitates when reacting the water sample rich in CO2 with basalt minerals, such as anorthite, albite and diopside. So, what i'm doing is: adding those minerals as kinetics in the reactants and also, the kinetics of calcite (the one that I want to precipitate). I'm setting the concentration of calcite to 0 and rate constant of 5.01e-5 (i'm not sure if that's correct) . However, when I run the reaction, and go to the graphic, I don't see the mineral calcite precipitating, only the ones that I added a concentration. I was using PHREEQC before and regarding this step (not the kinetics) was much easier to understand. I'm attaching the file, so if someone could take a look at it , i'd be happy amostra 8- reagindo com rocha.rea Quote Link to comment Share on other sites More sharing options...
