Rates of Reaction Plan Calcium carbonate and hydrochloric acid react together. I am going to investigate the rates of reaction of limestone chips CaCO3 in hydrochloric acid under different temperatures. I will monitor r the rate of reaction. Five factors that affect the rate of reaction are concentration of the acid, temperature, pressure, catalyst and particle size (surface area). In this experiment it will be the temperature of the hydrochloric acid and the surface area of the calcium carbonate. I will be keeping all factors constant except for one variable which will be th temperature during each experiment. Prediction I predict that the rate of reaction will increase proportionally with the temperature. Which can be explained by the collision theory, which is that the rate of reaction simply depends on how hard or soft the reacting particles collide with each other. The basic idea is that particles have to collide in order to react, and they have to collide hard enough as well. I have drawn a graph to illustrate my prediction: Fair Testing To keep it a fair test, the variables need to be kept the same to prevent getting the wrong results. The temper
