WebOct 1, 2024 · Factors That Affect Reaction Rate Several factors that influence the rate of a chemical reaction: Temperature: Usually this is a key factor. In more cases, raising the temperature increases the rate of a reaction because higher kinetic energy leads to more collisions between reactant particles. WebMar 26, 2016 · An increase in temperature corresponds to an increase in the average kinetic energy of the particles in a reacting mixture — the particles move faster, colliding more frequently and with greater energy. Increasing concentration tends to increase the reaction rate. The reason for this trend also has to do with collisions.
