An Nguyen 11P EXPERIMENT TO SEE HOW SURFACE AREA WILL EFFECT THE RATE OF REACTION Aim To investigate how surface area effects the rate of reaction in Calcium Carbonate. Theory This experiment is working on the theory of diffusion. Diffusion is the movement of particles. Three main things effect the rate of diffusion: - The distance of particles. Diffusion is quickest in gases as gas has a larger space between molecules making diffusion occur faster. - The energy of particles. The temperature effects the rate of reaction because the higher the temperature the faster the reaction. - The mass of particles. The effect of mass is caused by the relationship between the speed of particles and their temperature. Diffusion occurs in all the states of matter. However they most noticeably take place in liquids and gases. An example of this is Brownian Motion. Robert Browning noticed that when looking under a microscope pollen grains were moving in...
