Rates of Reaction Planning To measure the rates of reaction three variables were used. Firstly, a basic experiment was set up this was a delivery tube connecting a test tube filled with water in a bowl of water to a flask with calcium carbonate with a solution of hydrochloric acid. Various sizes of calcium carbonate was used (large, medium and powered particles) each variable was tested 4 times. As the particles and acid were mixed together the time was recorded to see how long the mass (test tube of water) took to decrease. The time was recorded at every 2cm³ interval. The results collected were the seconds the mass decreased to 2cm³, 4cm³, 6cm³ 8cm³ and 10cm³. The different particles are varied to show if the surface area has an effect on the rate the reaction. The second variable was the concentration of the acid. The same experiment was carried out but this...
