Rate of Reaction Aim: In this experiment we will find out what affect the surface area has on the rate of reaction. Background Knowledge: Surface Area - the reaction between the magnesium and acid in much faster when the magnesium is powdered: Reactions Particles can only react if they collide with enough energy for the reaction to take place. This theory is called the Collision Theory. There are four factors that can affect the rate of a chemical reaction, temperature, concentration, surface area and the use of a suitable catalyst. Using powdered reactants instead of a lump means the Collision Theory is greater, which means a greater area of reactant is exposed and so available for a collision. More collisions speed up a successful reaction. Apparatus: The chemical equation for the reaction between marble chips (also known as calcium carbonate chips) and hydrochloric acid: CaCO3 + 2HCL › CaCl2 + H2O+CO2 We will be following the reaction by collecting CO2...
