There are several factors that can influence chemical reaction rate. In general, a factor that increases the number of collisions between particles will increase the reaction rate and a factor that decreases the number of collisions between particles will decrease the chemical reaction rate.
Factors that influence the rate of a chemical reaction include temperature, state of matter of reactants, concentration, presence of catalysts, and pressure. PM Images, Getty Images. Anne Marie Helmenstine, Ph.D.or solids, the shape and size of the reactants makes a big difference in the reaction rate. Presence of Catalysts and Competitors. Catalysts (e.g., enzymes) lower the activation energy of a chemical reaction and increase the rate of a chemical reaction without being consumed in the process.
