The problem given: Many statues and buildings are made from calcium carbonate (CaCO3 ). This is a material, which reacts with acid. Unfortunately in recent decades people have placed chemicals into the atmosphere, which have contributed to the problem, known as acid rain. This has resulted in building materials such as limestone and marble being worn away. Aim: The aim was to plan and conduct an investigation into the factors that affect the rate at which acid reacts with marble. Background Theory: Here is the reaction, which will take place HCl + CaCO3 CaCl3 + CO2 + H2O There many factors that affect the rate of reaction. Here are a few of them: Collision Theory: The collision theory states that in order for a molecular collision to be effective it must meet two conditions: 1. The collision must have sufficient enough impact energy to overcome the Activation Energy. The Activation energy is the minimum energy necessary...
