Rates of reaction In Chemistry we were doing a topic on rates of reaction. I have found out that a reaction rate can be changed by changing concentration, Temperature, surface area and adding catalyst. In this reaction I am going to investigate the changing of the concentration. I have seen in other experiment increasing the concentration one of the chemical makes the reaction go faster. By doing this the rate will increase. In this reaction sulphur is formed and it is a yellow solid and makes the solution go cloudy. In my coursework I am going to investigate the reaction between hydrochloric acid and calcium carbonate. The word equation for this reaction is: Hydrochloric + Calcium Calcium + Water Acid Carbonate Chloride +Carbon Dioxide The symbol equation is: 2HCL (aq) + CaCO3 CaCL2 (aq) H20 ( l ) + CO2 (g) Key Variables All the substances are made up of some particles. The particles could be atoms, molecules...
