Aim To investigate the individual factors which affect the rate of reaction between Magnesium and Hydrochloric acid. Background Information For a reaction to take place between two or more substances, in this case magnesium and hydrochloric acid, the reactants must first collide with each other. However, they also have to collide with a minimum amount of energy for a reaction to occur. This is called activation energy. The word equation for, when magnesium reacts with hydrochloric acid is: Magnesium + Hydrochloric acid Magnesium chloride + Hydrogen By looking at this equation I can tell that this will be an exothermic reaction, as hydrogen will be released in the form of energy. To explain this exothermic reaction, there is a simple energy profile below which helps to describe how the activation energy works. The graph above shows how much activation energy is needed for the particles to react for an exothermic reaction. If the particles collide with less...
