Aim: To find out whether concentration affects the rate of reaction in an experiment. Introduction: There are five main variants in controlling the rates of reaction. That is surface area, concentration, pressure, light and catalysts/inhibitors. With surface area the larger the surface the faster the rate of reaction, this is because there is more surface for the solution to act on. For pressure the higher the pressure the faster the rate of reaction, due to the amount of collisions. Light does not affect many reactions except photo chemical ones. Catalysts have the ability to speed up a reaction without having any physical change inflicted on it. On the other hand inhibitors slow down reactions (which does not apply to this coursework). Finally concentration is when higher the concentration the faster the reaction, as there are more particles to fuse with and react therefore accelerating Equipment: Ceramic/ Plastic Beehives 3 Glass Measuring Cylinders Water Molars 0.25,...
