How does concentration affect the rate of reaction? Aim: To investigate how different concentrations of hydrochloric aci9d affect the rate of reaction on marble chip, (calcium carbonate). Background information: Different reactions take place at different rate. The measurement of the change can take place in a single unit of time; it can take seconds, minutes, hours and even days. It can be either fast or slow. Reaction rates are explained by the collision theory. The collision theory is explained by the rate of reaction. This is when reaching particles collide with each other. In order for particles to react, this depends on how often and how hard they collide. There are four main methods that are explained in terms of increasing the number of collisions so that the rate of reaction also increases between the reacting particles. These are: Temperature, concentration, surface area and a catalyst. Temperature causes particles to collide...
