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.
Chemical reactions proceed at different rates. The factors that affect reaction rates are: 1  surface area of a solid reactant. 2  concentration or pressure of a reactant. 3  temperature. 4  nature of the reactants. 5  presence/absence of a catalyst.
