Rate of reaction coursework analysis

I think this because there is outliers in the 2M set of data and the error bars overlap between 1M and 2M on my error bar graph.

graph of rate of reaction against temperature

If you are varying temperature, you need to heat up the reactant solutions separately and take their temperatures, mix, start stopwatch.

Your recorded results should indicate the accuracy of the measuring equipment e.

Rate of reaction coursework analysis

This sets the scene. It's all about chance! There are a few mild outliers. For the hydrochloric acid - sodium thiosulphate reaction think about the precipitate, observing it etc. When the solution is made more concentrated, there are a greater number of molecules in the same space. I would do different trials on sulphuric acid and nitric acid. For example, when my concentration was 1M the average reaction time was seconds, and then when the concentration was 5M the average reaction time was seconds. In this coursework, I will include background knowledge, prediction, safety, results, calculations, graphs, an analysis, conclusion and an evaluation.

Using white paper helped the marking to stand out. I also made sure that the measuring cylinder was on a level surface so that I could clearly see how much liquid I was putting in to it.

The timer was stopped when in see the black cross through the cloudy solution could no longer.

Rate of reaction graph explanation

For the hydrochloric acid - sodium thiosulphate reaction think about the precipitate, observing it etc. This ensures that the solution is completely opaque when I stop the timer. The points in the top right are quite far down so this shows a negative correlation. Organic chemistry makes me most enthusiastic, particularly optical isomers. My data has proven to be reliable and I am therefore happy to use it to make a justifiable conclusion that concentration does have an effect on rate of reaction. Construction dissertations online Rusting Rates of Iron Nails may be expressed as the reciprocal of the reaction time.. The factors to discuss might be: amount of limestone? Burning and explosions are very fast reactions: they have a high rate of reaction. Some of the work done here in presenting the results, e. The independent variables in our experiment are the concentration of hydrochloric acid. I could test this by asking one of my peers to follow the instructions and then asking for their feedback. So what we are after is the main 'trend s ' or 'pattern s ' describing with reference to the graphs. Cover letter phd application molecular biology Introduction My investigation is about the rate of reaction. The results are initially processed into graphical form 'graphing' for several reasons for both the analysis and evaluating the experimental This is because when there are more molecules in the solution, there are more molecules to collide so this will speed up the reaction, and therefore it is more likely they will collide with each other.

I could test this by asking one of my peers to follow the instructions and then asking for their feedback. I wrote down my results and then moved on to the next concentration of sodium thiosulphate.

rate of reaction practical

I have highlighted the 2M results on my tables because it seems as though there is a problem with that set. Keep the size of my measuring flask is the same size; this should hopefully make my experiment much fairer and accurate.

This causes a quicker reaction. When interviewed, boys also preferred coursework lessons although they were a lot more willing to do textbook questions without needing an understanding of the processes they were carrying out.

rate of reaction concentration experiment

In your 'method' description use the correct units or descriptors. If you haven't already chosen the VARIABLE, do so now, and make a prediction and justify it with some theory which you may have previously described and should refer to.

My Error bar graph shows a negative correlation.

Rates of reaction graphs worksheet

For different the acid concentrations you can do a 2nd and more advanced graphical analysis of the limestone results. I tucked in my tie and shirt, and took off my blazer. The results are initially processed into graphical form 'graphing' for several reasons for both the analysis and evaluating the experimental If you are doing something like the hydrochloric acid - sodium thiosulphate reaction, your reaction time measures the formation of a fixed amount of sulphur per 'time'. The system consists of a light beam emitter and sensor connected to computer and the reaction vessel is placed between the emitter and sensor. If you are confident and chosen the VARIABLE you want to investigate you should try to make a quantative prediction and maybe justify it with some theory if you can. Using white paper helped the marking to stand out.
