The Reaction Between Calcium Carbonate and Hydrochloric Acid Planning Aim I intend to find out the effects of changing the concentration of hydrochloric acid and the surface area of calcium carbonate on the rate of reaction in the reaction below: Calcium + Hydrochloric Calcium + Water + Carbon Dioxide Carbonate Acid Chloride CaCO3 + 2HCL CaCl2 + H2O + CO2 Scientific Knowledge> Chemical reactions can take place at different speeds.> A reaction which is over in a fraction of a second is a very fast reaction i.e. it has a high rate of reaction. As the time taken for the reaction to be completed increases, the rate of reaction decreases. That is: Rate of Reaction ? 1/Time> Increasing the concentration of reactants increases the rate of reaction.> Increasing the pressure of gases increases the rate of reaction.> In both cases, there are more collisions between particles which could lead to more successful outcomes, and hence a faster...
