Study Notes
Factors Affecting Reaction Rate
-
Reactant Concentration: Higher reactant concentrations lead to more frequent particle collisions, accelerating the reaction.
-
Reactant Nature and State: The chemical properties and physical states (solid, liquid, gas) of reactants influence the reaction rate. Molecular structure also plays a role.
-
Surface Area: A larger surface area between reactants facilitates more collisions and increases the reaction rate.
-
Temperature: Higher temperatures provide more energy to particles, increasing their movement and collision frequency, thus speeding up the reaction.
-
Catalyst Presence: Catalysts increase reaction rates by lowering the activation energy needed for a reaction to occur, without being consumed in the process.
