Multi-State Steric Mass Action¶
Group /input/model/unit_XXX/adsorption – ADSORPTION_MODEL = MULTISTATE_STERIC_MASS_ACTION
IS_KINETICSelects kinetic or quasi-stationary adsorption mode: 1 = kinetic, 0 = quasi-stationary. If a single value is given, the mode is set for all bound states. Otherwise, the adsorption mode is set for each bound state separately.
