Multiple kinetics simulation

Hi, I'm performing the dissolution of calcite in seawater with CO2, under pressure.
In the software it is present the kinetic rate for calcite, if I define the one for CO2, it is possible to perfom a double kinetics analysis? In order to see at each step how much CO2 and how much calcite dissolved in seawater?
thank you

Yes, you can have multiple kinetic reactions in KINETICS, one for Calcite and one for CO2(g) with corresponding RATES definitions. The amount of each that reacts is in the output or can be obtained with the function KIN_DELTA.
If the partial pressure of CO2(g) is fixed, you could define CO2(g) in EQUILIBRIUM_PHASES instead of KINETICS. The moles of CO2 added will be in the output, or can be obtained with the function EQUI_DELTA.
