INVESTIGATION The problem: To investigate a factor which affects the rate of reaction between magnesium and hydrochloric acid Background Knowledge: Kinetic theory In order for a chemical reaction to occur, the following factors must be taken into account: .the reagent particles must collide with each other. .the collision must have enough energy if a reaction is to take place. This energy is called the activation energy. This can be shown using simple diagrams. So that they are relevant to this investigation, the following diagrams will represent the reaction between magnesium and hydrochloric acid: Mg(s) + 2HCl(aq) MgCl2(aq) + H2(g) = acid particles = magnesium atoms Reaction Rates The rate of reaction (or reaction rate) defines the time it takes for the reactants of a reaction to turn into the products ie if it takes the reactants only a short time to turn into the products, then it is a fast reaction - therefore the speed, or rate, of...
