Investigating the effect of a concentration on the rate of reaction The rate of reaction tells us how quickly a chemical reaction happens. The rate is measured in time and can be useful to find out how much of the product is created in a certain amount of time, which can be useful in industry. The rate is measured from when the reactants are placed together, until they have finished reacting and created a product. Collision theory: chemical reactions only occur when reacting particles collide with each other with sufficient energy to react. (The essentials of AQA chemistry, Mary James) Activation energy: the energy needed to start a reaction Catalyst: a substance which speeds up a chemical reaction. At the end of the reaction, the catalyst is chemically unchanged. It lowers the activation energy. (Chemistry for You, Lawrie Ryan) Planning I have chosen to pursue and experiment to investigate the rates of reaction between Calcium Carbonate and...
