Exploration Question: How can temperature affect the rate of chemical reaction between Calcium Carbonate and Hydrochloric Acid?
Hypothesis: If temperature improves then the price of reaction between the reactants will increase because the molecules can gain more kinetic strength and produce it better to overcome the activation strength.
Self-employed Variable: Temperatures
Dependent Variable: Product manufactured in a arranged time
Constants: Time, attention
The well balanced equation:
CaCO3(s) + 2 HCl(aq) sama dengan CaCl2(aq) + CO2(g) + H2O(l)
Finding the uses:
(Using variable 1): Trials: 5. 7 ml, 5. 9 ml, 6th. 0 ml
Add all of them together: your five. 7 & 6. zero + your five. 9 sama dengan 17. 6
Then divide it by simply 3: seventeen. 6 / 3 = 5. on the lookout for
Realization and Analysis:
Overall, my own data supports the speculation I have manufactured. There was a correlation between your temperature and the amount of gas that was developed. As the temperature elevated, the amount of gas produced increased because the reactions are taking place at better pay. There were a lot of random errors in this experiment such as the gas that was dropped during the experiment. The reason was because of the amount of time it takes to pour the HCL in the flask plus the amount of time to put on the arrêter makes the benefits inaccurate, because gas has been lost to the outside and that we cannot assess that, but also in the end it still have similar results. In the chart it implies that the percent of maximize was low but as we have to 52 C the proportion became larger. I believe that around the 42 ” 52 C selection is when the temperature can be high enough to overcome the activation energy, that is why the gas produced is at a far higher at the 52 ” 62 C range compared to the 22 ” 42 C range. The systematic mistake in this experiment is the temp, because the temperatures fluctuates?nternet site cannot find the temperature perfect with every try things out.
I believe the procedure was adopted really well nevertheless the whole system is really time-consuming. The hardest portion of the experiment was turning the cylinder inverted while not trying to lose virtually any water. Likewise, there was the condition of flowing the HCL inside the flask with the Calcium Carbonate after that putting the stopper about, because,?nternet site addressed before, it was losing gas to the outside which cause inaccuracy in the data. There were also the issue of stirring. I possess noticed that just about every experiment the stirring rate is different which can be caused by me.
There were a large number of limitations through this experiment, such as the instruments which were used and because of the tools that were utilized, the accurate of the test is lowered. There was also the temperature, which is a factor that was hard to hold constant as the temperature fluctuates and also the thermometer is not too correct. To improve this experiment We would like better musical instruments that can assess with more accuracy. Also discover a way so when we tip the cylinder inverted, no drinking water is lost during that process and finding a way to lose no gas that was produced while in the process of putting in the HCL and placing the arrêter on.
