Rates of Reaction Coursework Introduction A chemical reaction is the process in which substances change into other substances. Chemical reactions can only take place when atoms, molecules, or ions collide with each other in order to share or exchange electrons. What happens in chemical reactions is that bonds are broken down, and new ones are made instead. To start a chemical reaction, reactants are needed in order to mix and chemically combine to give products. The rate at which the products are formed is called the rate of reaction. In this investigation, the reactants that will be used are magnesium and hydrochloric acid. The products I will finish with will be magnesium chloride and hydrogen gas. Following the reactivity series, magnesium is shown as a more reactive chemical than hydrogen. In a displacement reaction, the more reactive metal will displace the less reactive metal from solutions of its compound. And so, this...
