Introduction: For two substances to react in the first place their particles must meet and collide. They must collide with enough force, sufficient amount of energy (called activation energy that is the energy needed to start a reaction) and in the right direction so a reaction can successfully occur. The rate of reaction is dependent on the number of successful collisions taking place. Some reactions are instantaneous, while some, like the metaphoric rock take millions of years. The rate of reaction can be calculated as the amount of product formed or used up per second. Title/ Aim: Investigating how varying the concentration of Hydrochloric acid affects the rate of reaction. Prediction/hypothesis: I predict that calcium carbonate and hydrochloric acid will react together and that the higher the concentration the faster the rate of reaction. This is because as you increase the concentration you increase the number of particles in turn increasing the...
