Rate of reaction In my piece of coursework I am going to investigate how concentration changes the rate of reaction. The chemicals I am going to be using will be magnesium and hydrochloric acid. The point of the experiment is to find out whether dilute or concentrated acid will react better with the magnesium. The formula and word equation for this is: Magnesium + hydrochloric acid = magnesium chloride + hydrogen. Mg+ 2HCl = MgCl2 + H2 Background knowledge The rate of reaction can be affected by four main factors which include temperature, concentration, surface area and catalysts. 1 Temperature- When gases or liquids are heated the particles gain kinetic energy and move faster. The increased speed increases the chance of a collision occurring between reactant molecules and the rate of reaction increases, before there are any chemical changes. The molecules have to have a collision and at minimum kinetic energy to fuse or...
