Time how long it takes for the magnesium to completely finish reacting with the acid and put it into your results. The minimum amount of kinetic movement energy that two particles need if they are going to react when they collide is called the activation energy.
This also makes the 0. The scatter around best fit of the graphs for mass loss is minimal and the curves seem to be very smooth. As for the difference between concentrations, there is definitely a strong affect as the lowest concentration averages 7.
A catalyst leaver the activation energy. A solid in a solution can only react when particles collide with the surface of this solid, in this case calcium carbonate. However they all seem to be quite near 0.
Before I do this experiment I will do a preliminary test because it will help me understand what is happening, see if it is a fair test and if it is suitable for the investigation. Also I made absolutely sure that I was as accurate as I possibly could be.
There are therefore two main ways of increasing the rate of a reaction: This has helped me in the understanding of my present experiment because it gave me practice on how to take the temperature and helped me on how to accurately record the times of the experiment.
Methods of Measurement Independent Size and Surface area of the CaCO3 particle; in chip of approximately 3x3x3 mm in size or in powder form.
I received plenty of results to come to a conclusion and if I could do it again, I would do more variables and test each variable one or two more times so that I can pick out the best three for each variable.
The bigger the area of the solid surface, the more particles can collide with it per second therefore the faster is the rate of the reaction between hydrochloric acid and marble chips.
A powder has the largest surface area and will have the fastest reaction rate. If they collide, with enough energy then they will react.
I will then section the graphs into 4, every 2 minutes so I can compare what is happening in each section and why. So therefore, the more particles you have in a space, the more likely they going to collide. The curves of mass loss level of at different levels because the acid runs out at different times and at different amounts of mass loss, as the concentration goes down the mount of HCl molecules decreases and so less carbon dioxide can be produced as less successful collision can take place.
The only anomalies that can be identified on the mass loss graph are that the mass loss at the beginning of the experiment for 1.John Yeager AP Chemistry October 12, #7 Kinetics: Rate of Reactions Lab The purpose of preforming the Rate of Reactions lab is to observe the reaction and reaction rate of CaCO3 and HCl at several different concentrations, then also to change one variable of the lab to see if the results from the change test differs from previous tests.
Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Essay - Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid.
The rate of reaction with CaCO3 Essay. B. Pages:7 Words This is just a sample. Concentration increase the rate of reaction because if you increase the concentration of a substance you put more and more of it in a defined space therefore having a lot of reactant molecules in a defined space creating more chances of collisions between.
An investigation on how different concentrations of one type of reactant (Hydrochloric acid) affect the rate of reaction between marble chips (CaCO3) and hydrochloric acid (HCl) by measuring the volume of carbon dioxide (CO2) produced.
Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas. One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction.
Rates of Reaction: Hydrochloric Acid + Calcium Carbonate Essay Sample Background Information: Hydrochloric acid is a clear, colourless, highly-pungent solution of hydrogen chloride (HCl) in water.
It is a highly corrosive, strong mineral acid with many industrial uses.Download
