Chemistry coursework rates of reaction Background theory For a reaction to take place the two or how ever many different types of particle have to collide. The faster and more of the particles colliding the faster the reaction will go. To increase the speed of the reaction you can put more energy in to the reaction, the more energy in the reaction the more likely the particles are to overcome the activation energy. The activation energy is the amount of energy needed for the reaction to take place. There five ways of increasing the speed of a reaction these are; Increasing the concentration If the concentration of a solution is increased there are more reactant particles per unit volume. This increase the probability of reactant particles colliding with each other. Surface area If a solid is powdered then there is a greater surface area available for a reaction, compared to the same mass of un powdered...
