The affect of surface area on rate of reaction Aim: How does the surface area affect the rate of a reaction when marble chips are put in Hydrochloric Acid? Background Information: We are going to be looking at marble chips and acid. We will put Calcium Carbonate in the Hydrochloric Acid. Calcium Carbonate + Hydrochloric Acid Calcium Chloride + Water + Carbon Dioxide CaCO3 + 2HCl CaCl2 + H2O + CO2 We are using this very specific experiment because it releases a gas and is easy to measure the speed at which the gas is released. Prediction: The amount of marble chips will change the rate of the reaction. Therefore this means the bigger the surface area of the marble chips put into the Hydrochloric Acid, the quicker the rate of the reaction. This was predicted because in order for the marble chips and the Hydrochloric Acid to react with each other, collisions must...
