Preliminary Experiment Aim In this experiment I have the choice to change any variable to see what effects it could have. I am changing the temperature of the hydrochloric acid to investigate the rates of which the Calcium Carbonate reacts with it, and to discover what amount at which temperatures release a more quantity of gas (carbon dioxide). Prediction I predict that as the temperature increase, the average Speed of particles increase as well. At high temperatures, there are more collisions per second and this results in an increase in the rate of reaction. A reaction will only occur if the colliding particles possess more than a certain minimum amount of energy. This minimum energy for a reaction to occur is known as the activation energy. EA. The activation energy enables chemical bonds to stretch and break the rearrangements of the atom, ions and electrons to occur as the reaction proceeds. As a result...
