AIM In this investigation my aim is to find out the effect of concentration on the rate of reaction of limestone with hydrochloric acid. Calcium Carbonate + Hydrochloric Acid --> Carbon Dioxide + Calcium Chloride (Limestone) + Water CaCO3 + 2HCL --> CO2 + CaCl2 + H2O VARIABLE 1. Temperature: When the temperature is increased, the particles all move more quickly. But if they're moving quickly, they're going to have more collisions. 2. Concentration: If the solution is made more concentrated it means there are more particles of reactant knocking about between water molecules, which makes collisions between important particles more likely. In a gas, increasing the pressure means the molecules are more squashed up together so there are going to be more collisions. 3. Surface Area If one of the reactants is a solid then breaking it up into smaller pieces will increase its surface area. This means the particles around it in the solution will have more area to...
