Gcse Practical Assessment: Chemistry: Rates of Reactions Aim: To investigate one of these factors in order to show its effect on the rate of the following reaction: Factors, which affect the rate of a reaction: 1. Surface area (i.e. smaller marble chips have a larger surface area than larger marble chips) 2. Concentration 3. Temperature 4. Catalysts The Reaction: Calcium Carbonate + Hydrochloric Calcium Chloride + Carbon + Water Acid Dioxide CaCo3 + 2HCl CaCl2 + CO2 + H2O I have chosen to see the difference Concentration makes to the rate of the reaction between Calcium Carbonate and Hydrochloric acid. I chose Concentration because you can easily alter the amounts of concentration that you need Prediction: My prediction is that as the concentration of the hydrochloric acid increases, the rate of the reaction will increase as well, so therefore, the more concentrated the acid, the faster the reaction will become, or vice versa, the less concentrated the acid I the slower the...
