Quantification in catalysis is not without challenges. Some of these include:
1. Complex Reaction Mechanisms: Understanding and modeling complex reaction pathways can be difficult. 2. Mass and Heat Transfer Limitations: These can affect the accuracy of kinetic measurements. 3. Deactivation and Poisoning: Catalysts may lose activity over time due to deactivation or poisoning, complicating long-term quantification. 4. Reproducibility: Ensuring consistent and reproducible measurements across different experimental setups can be challenging.
