Several key parameters should be controlled to maintain consistent reaction conditions:
Temperature: Most catalytic reactions are temperature-dependent. A slight deviation can lead to a significant change in reaction rates and product distribution. Pressure: For gas-phase reactions, pressure can influence the rate and direction of the reaction, especially in heterogeneous catalysis. pH: In aqueous-phase reactions, pH can affect the ionization states of the reactants and the catalyst, altering their reactivity. Concentration: The concentrations of reactants, catalysts, and solvents can impact the reaction kinetics and equilibrium. Mixing: Proper mixing ensures uniform distribution of reactants and catalysts, preventing localized variations in reaction conditions.
