Coursework Kelly Waites Rate Of Reaction Aim My aim is to investigate the factors that affect rate of reaction. Theory The rate of reaction tells us how quickly a chemical reaction happens. The rate can be determined by the speed with which one of the reactants is used up or the speed that one of the products is made. Time is a critical factor in the rate of any reaction. There are a number of factors that affect the rate of a reaction. These are: . Surface area . Concentration . Temperature Effect of surface area Small pieces of solids, especially powder, react faster than large pieces. Surface area is measured of how much surface is exposed. As we increase the surface area, we increase the rate of reaction. For example, a nail. Only the iron atoms on the surface can react. If you cut the nail up, more iron atoms are exposed and ready to react: Collision Theory All substances are made...
