Investigation: How does channging the concentration of a substance affect the rate of reaction?

A chemical reaction is the process by which atoms or groups of atoms ar redistributed, resulting in a change in the molecular firearm of substances.

The reaction rate is how quickly a reaction occurs. I will be development the reaction rate during my probe to see how the intentness of acid effects the reaction rate. To do this I will be using the following reaction

Hydrochloric + atomic number 20         Ü         Calcium + Carbon +                  Water         

Acid                   Carbonate         Chloride Dioxide                  

                  powder         

2HCl         +         CaCO3         Ü         CaCl2          + carbonic acid gas         +         H2O

I will be using these substances because I know from my interrogation and previous experiment that these two substances react well together. So, I will be able to have quick and economic experiments.

I will be using the following equipment and setting the equipment up as shown in the diagram.

1.         Conical Flask

2.         Gas Syringe

3.         Rubber plug

4.          snatch Clock

5.         Top Pan Balance

6.         Heat Proof mat

7.          clamp and Boss

8.



        Clamp Stand         

I will be testing to see how the concentration of the hydrochloric acid effects the reaction rate. I will be able to see this by measuring the gas using the gas syringe. As carbon dioxide is released during the experiment, I will musical rhythm how much carbon dioxide will be produced in certain amounts of time. I will then draw a interpret to show how much carbon dioxide had been produced in several time intervals. I will then take the gradient at one point in the graph where each landmark is straight.

This will show me the reaction rate of each experiment. I will use five different concentrations of acid. Below ar the different concentrations I will be using.

Quantity of HCl (ml)         Quantity of...
