Science Coursework The speed of a chemical reaction is known as the rate of reaction. Rate is measured in two ways: measuring how much reactant is used up or how much product is produced in a certain amount of time. The rate of reaction is often shown in graph form due to the fact that the graph can be used to measure the rate at any given time. For example: CaCO3 + HCl --> CaCl2 + H2O + CO2 We can measure either how quickly CaCO3 or HCl is used up, or measure how much CO2 or CaCl2 is produced. The graph would then be as follows: The collision theory is the simple notion of particles of a substance having to crash together, therefore the name collision. The more collisions between particles in a given time, the faster the reaction. Rate of reaction can...
