How Does Temperature Affect The Rate Of Reaction
The graph shows the time it takes for the cross on the bottom of the beaker while the reaction is recurring to disappear. As it can be seen in the graph, the higher the temperature the shorter the time is for the Sulphur to be created. If it is looked as one continuous line, the first part of the trend line shows a steep, straight and constant decrease; then the 2nd part is not as steep and has a more gradual decline. Moreover, it shows how a reaction at 20°C a slower time for the cross to disappear compared to 40°C and especially 60°C. Both graphs show how temperature has a great effect on the speed of sulfur formation covering the X on the paper.

Therefore, it is clear to see the link between temperature and the rate of reaction of the chemical reaction.
Conclusion
In conclusion the effect temperature has on a chemical reaction is pretty clear, as it increases the rate of reaction. There is a strong, and positive correlation between these two factors, which are temperature and rate of reaction. It can be said, using graphs 1 and 2 as evidence that as temperature increases, the time it takes for Sulphur to form/for the cross on the paper to disappear goes faster as well. In graph 3, it shows the rate of reaction of all 3 temperatures. The graph is a clear visual support to the results of this experiment, it shows and validates the hypothesis. To properly answer the research question, due to the temperature change in each chemical reaction, the speed of the reaction increased as temperature increased because the heat allowed the reaction to speed up; furthermore, giving energy to the molecules in order for them to collide and finish the reaction more quickly. The hypothesis is acceptable for this experiment since it stated that the highest temperature would have the highest rate of reaction which was true, making the hypothesis reliable in this …show more content…
During the pilot test for my experiment, I noticed a problem with the method I originally had, I immediately figured out that I would not be able to heat up both solutions for 3 temperatures and for 2 trials using a conical flask; that would have been too time consuming and I assume I would not have been able to finish. Fortunately, I decide that test tubes would be a more logical option as it is smaller and I can fit both solutions in the water at the same time. That saved me a lot more time and I was able to almost finish my experiment under one lesson (I needed a couple of more minutes to finish the 2nd trial for 60°C, in another lesson). By changing my method I was able to properly perform my experiment and it allowed me the chance to do it well for real. I would have to say the current method is valid, as it clearly explains the steps needed to do this type of experiment. I was able to follow it and it helped me get all the results I needed. It’s safe to assume that in my experiment there might have been some errors in my method. Since I decided to heat up the solutions, once it reached the temperature required to create the reaction I took it out of the heated water; that could have caused the
