Several factors can lead to irreproducible results in catalysis. These include:
Catalyst preparation: Variations in the synthesis and treatment of catalysts can lead to differences in their activity and selectivity. Reaction conditions: Small changes in temperature, pressure, or reactant concentrations can significantly impact the outcome of catalytic reactions. Measurement techniques: Inconsistent or inaccurate measurement methods can result in data that cannot be reliably reproduced. Human error: Mistakes in data recording, sample handling, or procedural steps can introduce variability. Environmental factors: Uncontrolled variables such as humidity, light exposure, and contamination can affect catalytic performance.
