As you can see, small marble fragments have a steep slope than small and medium chips. This means that small marble debris has a fast reaction rate. The shape of the graph shows that the reaction starts sooner and later, and the final reaction stops. However, because the gas injector no longer contains 100 cm 3 of gas, the reaction for 90 seconds has not been completed. Our results seem to be accurate and reliable. There is no abnormality, these can be obtained through practical problems. Example: gas leakage, the plug is not tightly placed due to degassing, or the acid concentration may be slightly different, resulting in the least reliable as possible
In this survey we use CaCO 3 in the form of marble chips and react these chips with hydrochloric acid. The equation for this is as follows. PURPOSE: We are investigating whether the temperature affects the reaction rate of the experiment. The experiment I am doing is how temperature influences the release rate of gas when hydrochloric acid is added to calcium carbonate in the form of a marble chip. 2HCL (aq) + CaCO 3 (s)? H 2 O (I) + CO 2 (g) + CaCl 2 (aq) Preliminary experiment program, evaluation and prediction
The reaction rate is related to the rate at which this occurs. There are many variables that influence the reaction rate, but in this experiment we investigate the effect of concentration on reaction rate. Objective In this survey, I would like to investigate the influence of hydrochloric acid concentration on the reaction rate of marble chips (calcium carbonate). The plan I'm planning is between calcium carbonate (CaCO 3) (marble chip shape) and hydrochloric acid (HCl). Hydrochloric acid + calcium carbonate
I anticipate that adding a small piece of marble to hydrochloric acid makes the reaction faster and therefore more gas (carbon dioxide) released. This is due to the large surface area of small marble fragments. Addition of large marble chips to hydrochloric acid slows the reaction rate, resulting in less gas evolution. This is because marble chips have small surface area. This means that using smaller marble chips can produce 100 cubic centimeters of carbon dioxide faster.
