An Investigation to Find: How the Concentration of a Solution Affects Rates of Reaction In this investigation I am going to be investigating the rate of reaction between Hydrochloric Acid (HCl) and Calcium Carbonate (CaCO3). There are several factors that affect rates of reaction, and I could investigate any of these. These factors are: * Surface Area * Concentration * Temperature * Affects from Catalysts Surface Area: The rate of reaction is affected by the surface area of what is being reacted; in this case the surface area of the calcium carbonate. If the particles of calcium carbonate have a greater surface area (i.e. using many small particles rather a large chunk) the reaction time will decrease; and larger particles would take longer to react. This can be explained using the collision theory. For the reaction between hydrochloric acid and calcium carbonate to occur, the particles in the chemicals must collide with each other. The more the collisions occur, the...
