Sc1 Investigation To investigate the rate of reaction between calcium carbonate (marble chips) and hydrochloric acid. Planning. CaCO3 (s) + 2HCl (aq) ---- CaCl2 (aq) + H2O (l) + CO2 The rate of reaction depends on how hard and how often the reacting particles collide with each other. A rate of reaction is how fast a reaction takes place. The main variables that can change a rate of reaction are; 1. Temperature. 2. Concentration. 3. Surface area (of a solid). 4. A catalyst. 5. Pressure. 1. When the temperature is increased all the particles move quicker, therefore there are more collisions. 2. If the solution is made more concentrated there will be more particles of the reactant colliding between the water molecules which makes collisions between the reactants more likely. 3. If a reactant is a solid, then breaking it up into smaller pieces (but keeping the mass the same) will increase its surface area. If there is a larger surface area the reacting...
