Several factors can affect the reaction rate in catalysis: - [Temperature](): Increasing the temperature generally increases the reaction rate until a certain point. - [Pressure](): For gas-phase reactions, higher pressure can increase the reaction rate. - [Concentration](): Higher concentration of reactants usually leads to a higher reaction rate. - [Catalyst Properties](): The surface area, pore size, and the active sites of the catalyst play crucial roles. - [Inhibitors](): The presence of inhibitors can slow down the reaction rate.
