Hello again,


So I was putting dissolution rate parameters into a kinetic mineral in the reactants tab. When I would input the dissolution rate law, I had a species (SiO2(aq)) which is part of the function and is raised to a particular power. When putting the power dependency into the kinetics the stoichiometry of the rate constant changes from mol/(cm2*s) to mol.75kg.25/(cm2*s) for example. What does this imply?






Here is the attached gwb script:


The database is for 500 bars and at 300C....so don't necessarily try to run it

Hi Drew:


I'm not sure I understand the question. Units on the rate constant must change depending on how the rate law is posed. Note for instance when you add inhibiting/promoting species that rate constant units change depending on whether or not you cast the species as concentrations or activities.
