All three reactions result in the same amount of CO2 gas being produced; however the higher the concentration of HCl, the faster the rate of reaction, thus the less time it takes for the reaction to be complete.
The surface area is measured of how much area is exposed. Each experiment run will need 50 cm3. From the results in the table above, it can be worked out that the rate of reaction is directionally proportional to the concentration of hydrochloric acid, so if you halve the concentration of HCl will be halved, if you quarter the concentration, the rate will be quartered.
As for why the higher the concentration the quicker 50cm3 Carbon Dioxide is produced, I believe this is because Carbon Dioxide is produced in the reaction, and a higher concentration a faster rate of reaction.
During this investigation I will wear goggles due to health and safety rules. The values of n and m are usually 0, 1 or 2 corresponding to zero, first and second orders; however some reactions can have fractional or negative orders.
Orders of Reactions The reaction of calcium carbonate with hydrochloric acid is said to be first order with respect to hydrochloric acid.
Set up test tube next to each other in visible site Numbered each test tube with 1, 2, 3, and 4 written on the tape. This is probably down to human error, as there was no large difference in temperature that day.
Basically the higher the temperature roughly doubles the rate of many reactions. This would improve our results, as there is a time delay for the carbon dioxide to reach the end of the measuring cylinder. These outliers were probably caused by human error, as few other variables could have affected the experiment.
Temperature affects the rate of reaction as explained in Collision theory. Now to work out the order of the reaction with respect to X, in this case we need to use reaction 1 and 2: This relationship can be converted into a rate equation by replacing the proportionality sign with an equals sign and inserting a constant: So therefore, the more particles you have in a space, the more likely they going to collide.
Continue timing until no more gas appears to be given off. Surface Area; the smaller the pieces the larger the surface area becomes.
This process is based on random particle movement. The rate of a chemical reaction can be increased by: That is the main difference I would have made to our method, as the majority of the method was acceptable.
Measured out 3ml of diluted water in a ml measuring cylinder, and placed into the test tube with the label 4. When [X] is doubled the rate quadruples, this means that the order of the reaction with respect to [X] is 2.
However, there could have just been some strange results, and there was no human error which affected the results. This can be worked out by using values from the table:- An investigation to find out how the concentration of acid affects the rate of reaction between hydrochloric acid and calcium carbonate (magnesium ribbon) Planning The aim of my investigation is to find out how changing the concentration of acid affects the rate of.
The rate will decrease over time as the hydrochloric acid is used up (its concentration decreases). The rate of reaction could be worked out either by measuring the pH of the solution, the decrease in the mass of calcium carbonate, or the increase in the volume of carbon dioxide.
The graph above shows the volume of gas produced over time in the reaction between HCl and CaCO 3. Each reaction started. - An Investigation to see How the Concentration of Hydrochloric acid affects the Rate of Reaction with Calcium Carbonate I am going to investigate how concentration of hydrochloric acid affects the rate of reaction between hydrochloric acid and indigestion tablets which contain mainly calcium carbonate.
Mar 31, · rate of reaction between calcium carbonate chips and 1 and 2 mol per liter hydrochloric acid. calcium carbonate rate of reaction mi-centre.com4 John West. Introduction. We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid.
I will add calcium carbonate (marble chips) to hydrochloric acid/5(1). Is the reaction of calcium carbonate with hydrochloric acid zero order, The effect of concentration on rate – Teacher guidance. reaction of calcium carbonate and hydrochloric acid, and deduce the rate equation.
They use the rate equation to make predictions.Download
