Chemistry Coursework. Introduction There are four main factors affecting the reaction rate of an experiment, * Temperature * Concentration * Surface Area * Catalyst They can increase or decrease the rate of a reaction. This is due to the collision theory, which states that the reacting particles must 'bump' into each other with a sufficient energy, which is called the activation energy, or they will not react. Those four things either increase the chance of collisions between particles, or increase the force with which the particles collide. Which makes it more likely that the activation energy will be reached, which means a higher rate of reaction. It is important to remember that although these four factors affect the rate of reaction the do not increase the amount of product formed, the only to do that would be to increase the amount of reactants you put in at the beginning of the process. Temperature increases...
