Mario Creatura Rates of Reaction: Investigate the reaction between Magnesium (Mg) and Hydrochloric Acid (HCl) Planning Prediction I predict that as the concentration of the hydrochloric acid increases, the average rate of the reaction will decrease until it will be almost un-noticeable when the concentration reaches 0.0. I have made this prediction due to the informative work that I have executed previously to this experiment; involving rates of reaction of different solutions and substances. Through doing similar experiments and theory work I have discovered that the Collision theory plays a major part in understanding what elements affect the speed (rate) of the reaction. The Collision theory describes perfectly reaction rates. The theory states that the rate of a reaction depends on how often and how hard the reacting particles collide with each other. This therefore means that depending on the amount of collisions and the force that is put behind them depends on the speed of...
