Anomalies can occur due to a multitude of reasons including but not limited to:
1. Surface Effects: The surface properties of a catalyst, such as defects or irregularities, can lead to unexpected catalytic activity. 2. Reaction Conditions: Variations in temperature, pressure, and concentration can lead to anomalous behavior. 3. Catalyst Deactivation: Over time, catalysts can lose their activity due to poisoning, fouling, or sintering, leading to unexpected results. 4. Kinetic and Thermodynamic Factors: Sometimes, the reaction kinetics or thermodynamics deviate from the expected path, causing anomalies. 5. Intermediates and By-products: The formation of unexpected intermediates or by-products can alter the course of the reaction.
