Chemistry Coursework Aim - to investigate the effect of concentration of acid varies on the rate of the reaction Background Knowledge and Theory The equation of this reaction of this experiment I am going to investigate is like this: 2HCL (aq) + CaCO3 (s) --> CaCl2 (aq) + H2O (l) + CO2 (g) Hydrochloric acid + Calcium carbonate --> Calcium chloride + water + carbon dioxide Because of carbon dioxide have given out and it is a gas, the product can be collected by a gas syringe and measure the rate of reaction. (i.e. volume over time) Independent variables: 1. Concentration 2. Temperature 3. Surface Area 4. Air pressure 5. Catalyst I am going to investigate the concentration on the rate of reaction. For substances that may react, two things are necessary before they will react. * For reactions involving more than one substance, the particles must collide before any reaction is possible. * Not all collisions result in a reaction. Particles must collide with...
