specify if the amount of the kinetic reactant should be fixed to the initial amount during the simulation. Possible values: true (fixed); false (not fixed); default is false. Fixing the amount of a kinetic reactant may be desirable when the kinetic reactant is used to represents a reaction rate that transfers mass between other reactants. Note: fix_amount can only be used if a chemical_formula has been defined!
