The iodine clock mechanism I am going to investigate the effects of changing temperature and concentration has on the iodine clock reaction. Chemical reactions occur when particles collide. They must collide with a certain minimum energy called the activation energy. Diagrams Concentration of low particles. There aren't many collisions as the concentration is so low there is not much energy. Concentration higher more chance of particles colliding. There is more energy so there is more chance of collision. By kirsty skidmore Temperature low Not much chance of collision. As there is a low temperature there is not enough energy to make the particles collide. Temperature high There is more chance of collision. By kirsty skidmore By kirsty skidmore As there is a high temperature there is a higher amount of energy so there are more collisions. Since in the first experiment is to see how concentration makes a difference on the speed of the iodine clock reaction the dependent variable is time. For the...
