Chemistry coursework Aim: We are going to investigate how change in the concentration of acid affects the rate of reaction. Introduction: Chemical Reactions are caused when the particles collide with each other to react. This is known as collision theory. Particles need enough energy to make a successful reaction. This is called activation energy when the minimum amount of energy is present a reaction happens. The formula for the collision theory is 1/2 mv2.. Altering the following factors can increase the rate of reaction: Sizes of chips - Varying the size of chips will have an effect on the results ie the smaller the chips the less of a successful reaction takes places. Temperature - If the temperature is increased, the particles gain more kinetic energy, meaning they move further and faster. This means that collisions are more likely to happen, and will happen with more force, therefore speeding up the reaction time. Increasing the...
