... Rate of reaction between Calcium Carbonate and Hydrochloric Acid Aim: To investigate whether the concentration of hydrochloric acid affects the amount of carbon dioxide given off by marble chips while reacting with the acid. This is the word equation for my investigation: Hydrochloric Acid + Calcium Carbonate => Calcium Chloride + Carbon Dioxide + Water Introduction: A collision between particles is needed for a reaction to take place in order to form a product. Some collisions are successful and give a product while others do not because particles do not have enough energy. A theory named 'The Collision Theory' states that when there is a higher concentration, there are more particles therefore there are more collisions resulting in a higher reaction rate. This also applies to my experiment because, as the concentration of the acid increases, there are more acid particles in the same volume. Therefore there is a greater chance
