Rates of Reactions Aim: To investigate the rate of reaction using hydrochloric acid and water in different concentrations on marble chips. Prediction: Rates of reaction tell how quickly a chemical reaction happens. They take place at a variety of speeds. Precipitation reactions are very fast and are complete in a fraction of a second. Corrosion reactions are processes, which slowly corrode objects; this process can carry on for years. You can measure how fast these reactions are with any variable, such as the amount of hydrogen given off, etc. These reactions can be affected by: What the surface area of the reactants are. Diagram1 The concentration of the solution. Diagram 2 The temperature. Diagram 3 Whether catalysts are used. Diagram 4 I know from class that if you expose more particles in a given volume, (increase the surface area) there will be an increase in the rate of the reaction. Also if you...
