The effect of Concentration on Rates of Reaction A reaction happens when particles of two different reacting substances collide. Also, a fixed amount of energy known as the Activation energy level must be reached. There are five main factors, which affect the speed at which the Activation energy is reached; this speed is the rate of reaction. The five main factors, which affect the rate of reaction, are: TEMPERATURE, when the temperature is increased there will be more movement within the particles in the substance. Therefore there will be more successful collisions and the rate of reaction will be faster CATALYST, a catalyst is a separate substance, which speeds up the rate of reaction. However the catalyst remains left behind after the reaction has taken place. SURFACE AREA, if a larger piece of a reactant is broken down to simpler pieces, the second reactant will have a larger total area to react with. Therefore...
