Chemistry Coursework - Rates of Reaction The aim of my experiment is to test the speed that Carbon Dioxide (CO2) is given off during a reaction of Calcium Carbonate (CaCO3) and Hydrochloric Acid (HCl), where the concentration of the Hydrochloric acid (HCl) is variable. The speed of my the reactions will change because of the variable, concentration gradient. All reactions are affected by Particle Theory. For the particle theory to occur particles need to collide, without colliding particles, there would be no reaction. For a chemical reaction to take place, some bonds in the reactants must be broken. The colliding particles must have enough energy to break these bonds. This minimum amount of energy is called the 'activation energy'. Only the very fastest moving particles have enough energy to break bonds. In gases, liquids and in solution, the particles move at a range of speeds. Some are moving very slowly and others are moving...
