| time     | float   | Duration in hours                         |

## 📤 Outputs

| concentration_curves| dict/list | Time evolution of species concentrations   |
| radical_fluxes      | dict/list | Flux or generation rate of radical species |

## 🧠 Assumptions
- The model uses ordinary differential equations with mass-action kinetics.
- Radical generation from oxygen uptake is temperature-dependent.
- No external inhibitors or antioxidants are present unless specified in mixture.

## ⚠️ Limitations
- No spatial heterogeneity (0D model).
- Requires predefined mixture species and reactivity patterns.
- Output interpretation depends on naming conventions in `species.py`.
