Analysis An experiment to show Calcium Carbonate reacting with Hydrochloric Acid I drew 8 graphs, Graph 1 shows the volume of oxygen collected against time for all 6 concentrations (0.2, 0.5, 1, 1.2, 1.5 and 2.0) it shows how the rate is directionally proportional to the concentration, so as the rate doubles so does the concentration. I have also drawn out 6 separate graphs for each concentration. CaCO³ (s) + 2HCl (aq) --> CO2 (g) + H20 (l) + CaCl2 (aq) In order for the Calcium Carbonate and Hydrochloric acid particles to react with each other, they must collide with each other and the collision must have enough energy to do so. Collision theory basically means that the more collisions that occur, the faster the rate of reaction will be. So in this experiment when there are lots of collisions more carbon dioxide will be produced. From the information my graph gave me...
