Chemistry Coursework - An Investigation into how surface area effects the rate of the reaction? Aim To investigate how different factors affect the rate of the reaction, with one in specific detail, the temperature, and to see the effects when Marble Chips (CaCO3) and Hydrochloric Acid (HCl). Carbonates react with strong acids to give off CO2 and H2O. Marble is a form of Calcium Carbonate and therefore behaves in the same manner. Word Equation Calcium Carbonate + Hydrochloric Acid> Calcium Chloride + Carbon Dioxide + Water Balanced Symbol Equation CaCO3 + HCl> CACl2 + CO2 + H2O I will measure the volume (ml³) of CO2 produced by this reaction as a measure of the rate of reaction. Prediction I predict that there will be a positive correlation between the rate of reaction and temperature - as the temperature increases so to does the rate of reaction. For a reaction to occur not only must particles collide,...
