Rate of Reaction of HCl & Mg Lab Answers

rate of reaction lab report magnesium and hydrochloric acid

The Kinetic Molecular Theory states that temperature is a measure of average kinetic energy of the particles Thus, Due to the increase in temperature the average kinetic energy of the particles increases proportionally thus resulting in higher overall entropy. If I had a wide range of molarities, it would be easy to see this pattern. At the same time, the timer was started. The volume of sodium thiosulphate will remain unaffected throughout the whole experiment, Where as I will be changing the concentrations of hydrochloric acid. The variables that could affect the rate of reaction are: 脗路 Temperature 脗路 Concentration of Acid 脗路 Surface Area 脗路 Increase Pressure this is not applicable in this experiment 脗路 Catalyst this is not applicable in this experiment 脗路 Volume 脗路 Mass of Calcium Carbonate 脗路 S. Controlled Variables Why does it need to be controlled? The one major problem with my experiment was that I did not continue to measure the amount of gas produced for enough time so I could not see that all the lines in my graph would level of and meet at the same place I could solve this easily by repeating the experiment and taking reading every twenty seconds for longer than I did for about five minutes instead of the previous two. 路 I will note down in my table how much gas is in the syringe every 20 seconds for 120 seconds.

I think that the results will go slower and鈥 1059 Words 5 Pages of temperature on the reaction rate of hydrochloric acid and magnesium. In the final part of phase one which was steps 9-11, five different metals were placed in Hydrochloric acid. . You can see this by looking at the lines of best fit on my graph and seeing that they get steeper to confirm my prediction I calculated the rate of reaction from my graph I did this by taking two points on the graph and drawing a line down on the highest point line a and across on the lowest point line b and drawing until they join and make a triangle I then divided the length of line 'a' by the length of line 'b'. I am going to record the amount of gas produced by the reaction in two minutes.

Enzymes are very particular, one specific enzyme can only speed up one specific reaction. To investigate鈥 Chemical reactions can be categorized based on the release or absorption of energy. Most people put food in their mouth, chew a few times and swallow their food, as if their sole focus was how quickly they could get their foods to their stomachs. The temperature that the reaction is occurring at The temperature at which the reaction is taking place should be kept constant. Because of this, the moment that you can no longer see through the solution can be used as a consistent way to stop time.

Follow your instructor's directions for submitting the lab report. Based on your experiment, how many milliliters of H2 would be produced had 0. Measure the boat after the magnesium has been poured to and subtract the first weight from the second to see how much magnesium has been used. Use it to explain why each factor tested in this experiment altered the rate of the reaction. In order for cells to efficiently manage thousands of different chemical reactions, they make use of biological catalysts.

The hydrochloric acid will react much faster with hot sodium thiosulphate as the particles will move around much faster than if they were reacting with the cold sodium thiosulphate the kinetic theory. The dependent variable for all of the investigations was the time it took for the reaction to occur. Ensure that there are no naked flames. Not a single group had one weird outlier or a graph with seemingly random points all over the place! Laboratory Report Review the Guidelines for Writing Laboratory Reports The laboratory report for this experiment will be a group report. Pour the acid into the 100 cm3 conical flask.

How does the length of Magnesium affect the rate of reaction?

rate of reaction lab report magnesium and hydrochloric acid

Temperature influences the rates of reaction through kinetic energy, such that high temperatures increase the kinetic energy of reacting molecules therefore causing frequent collisions, which form products faster. Practical Chemistry activities accompany and. 路 The amount of gas produced by the reaction in a certain amount of time. I think this because of the Collision theory. It is best if the students work in pairs because setting up and starting the experiment requires more than one pair of hands.

These two theories justify the corresponding increase of both factors. The readings could have also been made more accurate if we got down at eye level with the tube and got the exact readings at teh time needed. For my experiment the results will be measured with a stop clock and the length of time the magnesium takes to dissolve will be measured. So technically, a measurement of 0. In both situations the graders accepted either value for k. I will look at the various factors affecting the reaction and select one variable to change, while the others keep constant in order to carry out a deta.

The symbol for an ohm is 鈩 Here is the rule for working out the鈥 Introduction: Enzymes are biological molecules that act as a catalyst to significantly speed up the rate of the chemical reactions that take place within cells without being used up in the process. Repeat steps 5, 6 for a second trial 8. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. Though I used this experiment to primarily investigate collision theory and different factors that affect the time it takes for a reaction to complete, it could easily be used to determine something more complex like reaction order. To find out how the temperature of acid effects the rate of the reaction between Hydrochloric Acid and Calcium Carbonate.
