Final answer:
Temperature, catalysts, and reactant concentration influence the rate of a reaction.
Explanation:
Factors Influencing Reaction Rate:
Temperature: Increasing temperature generally increases reaction rates by providing more kinetic energy to reactant molecules.
A Catalyst: Catalysts lower the activation energy required for a reaction, speeding up the process without being consumed.
Reactant Concentration: Higher concentration of reactants leads to more collisions, increasing the chance of effective collisions and thus reaction rate.
