Factors, Which Affect the Rate of Reaction There are certain factors which affect the rates of reaction in an experiment. These factors are: * Pressure * Temperature * Concentration * Surface area / particle size and * The addition of a catalyst The factors that I will be concentrating on are temperature, concentration and surface area / particle size. Pressure Pressure influences the rate of reaction only when the reactants are in their gas phase. Pressure does not affect them much when they are either solids or liquids. By increasing the pressure, you squeeze the molecules together so you will increase the frequency of collisions between them and their surrounding container. Temperature When the temperature of a reaction increases, heat is supplied to the particles of the reactants involved. This heat energy is converted into kinetic energy which all of the particles acquire. This means that more particles collide with each other per second. In addition, the faster the particles are...
