What are the Key Parameters in Catalytic Reactions?
Several key parameters influence the kinetics of catalytic reactions:
Rate Constant (k): This is a proportionality constant in the rate equation that is specific to a particular reaction and conditions. Activation Energy (Ea): The minimum energy required for a reaction to proceed. Catalysts lower this energy barrier. Reaction Order: The power to which the concentration of a reactant is raised in the rate law. This can change in the presence of a catalyst. Turnover Frequency (TOF): This measures the number of catalytic cycles a catalyst site undergoes per unit time. Selectivity: The ability of a catalyst to direct the reaction to a specific product, minimizing side reactions.
