Rates of Reaction Coursework Experiment to see how the Concentration of Acid Changes the Rate of Reaction Plan In this practical I am going to add marble chips, a form of calcium carbonate, to hydrochloric acid and collect the gas produced into a gas syringe. Then I am going to change the concentration of the acid and see how the rate of the reaction changes as a consequence of this. The reaction that is going to take place is the one below: Calcium Carbonate + Hydrochloric Acid ( Calcium Carbonate + Water + Carbon Dioxide CaCO3 (s) + HCl (aq) ( CaCl2 (aq) + H2O (l) + CO2 (g) The gas produced is carbon dioxide. The fastest reaction will be the one which takes the least time to fill up the gas syringe. The apparatus are shown below in the positions that they will be used: The rate of reaction will dependant on the number of collisions and...
