How does rate of concentration affect the rate of reaction between marble chips and hydrochloric acid? Introduction We are going to investigate how the rate of reaction differs using varying concentrations of hydrochloric acid with marble chips. Prediction I think that the higher the molarity of the hydrochloric acid, the faster the reaction will occur because the less water molecules means the chances of acid and calcium carbonate particles colliding is greater. (If the acid was more dilute, it would contain more water molecules, meaning it would take longer for the particles to react with each other because the odds are reduced of them colliding. Planning CaCO3 + 2HCl(aq) CaCl2 (aq) H2O (l) + CO2 (g) Calcium + Hydrochloric Calcium Water + Carbon Carbonate Acid Chloride Dioxide To ensure a fair test, the following must be considered: * Temperature - to keep it the same or change it, reactions go faster under a higher temperature because the heat provides the...
