Coursework - An Investigation to see how Concentration Affects the Rate of Reaction Aim: To see if the concentration of Hydrochloric Acid affects the time it takes for Calcium Carbonate to produce certain amounts of Carbon Dioxide. Calcium Carbonate + Hydrochloric Acid --> Calcium Chloride + Carbon Dioxide + Water CaCOł + 2HCl --> CaCl˛ + CO˛ + H˛O Variables: Concentration is not the only variable that could be used for this experiment. Temperature, surface area, mass and volume, as well as concentration all effect the speed of a reaction. The rate of a reaction depends on how many successful collisions there are in a given amount of time. Temperature, this can change the acid's energy. When heat is added to the acid it gives all the particles more energy. When they have more energy they move around quicker and then have more chance of colliding, this is called the collision theory. This theory...
