Aim The experiment will be on the reaction of Nitric acid and marble chips. CaCO3 + 2HNO3 Ca(NO3)2 + CO2 + H2O This particular reaction is rather slow and so needs to be quicker by changing the factors that affect the rate of reaction. In order to make predictions I need to research on what factors there are and from that, I will be able to draw up a prediction for the experiment. Introduction There are five ways that the rate of reaction can be affected 1. Temperature 2. Surface area 3. Pressure in gaseous reactions 4. Concentration 5. Catalyst This is why: Temperature: Surface area: Pressure: High Pressure Low Pressure Concentration: Catalyst: All of these factors have something to do with the collision theory. The rate of reaction depends on how often and how hard the reacting particles collide with each other. The basic idea is that particles have to collide in order to react, and they have to collide hard enough as well. All of...
