Pressure plays a crucial role in catalytic reactions for several reasons:
Reaction Rate: Higher pressures can increase the concentration of reactant molecules, thereby enhancing the reaction rate. Equilibrium Shifts: According to Le Chatelier's principle, increasing pressure can shift the chemical equilibrium toward the side with fewer gas molecules, which can be beneficial in certain reactions. Phase Behavior: Pressure can influence the phase of reactants and products, affecting the overall reaction dynamics. Catalyst Stability: Some catalysts may require specific pressure conditions to remain stable and active over time.
