The Chemical Reaction Package dialog is used to solve the concentration change due to chemical reactions. The chemical reactions include linear or nonlinear sorption isotherms and first-order irreversible rate reactions (radioactive decay or biodegradation).
The dialog has the following options:
- Sorption – Select one of the following methods:
- "(none)"
- "Linear isotherm"
- "Freundich isotherm"
- "Langmuir isotherm"
- "First-order kinetic sorption (non-equilibrium)"
- "Dual-domain mass transfer (without sorption)
- "Dual-domain mass transfer (with sorption)"
- Kinetic rate reaction – Has the following options:
- "(none)"
- "First-order irreversible kinetic reaction"
- "Zero-order reaction (decay or production)"
- Variable input
- Layer by layer
- Cell by cell
- Specify IC of sorbed phase
- Layer
- Bulk density
- Immobile porosity
