I am going to investigate how the concentration of an acid affects the rate of reaction. The rate or speed of a chemical reaction is a measure of how fast the reaction takes place. There are a few factors that affect the rate of reaction: concentration, surface area, temperature and using a catalyst.
Concentration – as you know, particles in a solution move about, they bump into one another, this is the collision theory. If the concentration of the acid is increased, the number of ions moving about in the solution is increased, and therefore there will be an increase in the number of collisions. However not all of these collisions will have enough energy to react because they do not have enough energy to cross the activation energy barrier. Nonetheless, the more often that particles with enough energy to collide, the more chemical reaction will take place. I think that the rate of chemical reaction will increase if the concentration of reactants increased. I f the......
