Jump to navigation Jump to search. In order to get maximum marks in this coursework it is vital that you discuss all factors which affect the rate of a reaction. These include: Temperature. The higher the temperature the more energy there is within the reaction. When there is energy in the reaction more reactants hit each other and then there are more successful reactions. Miss Nichol shows you how to do the catalase rates of reaction coursework. Reactions that happen quickly have a Text 1 RATES OF REACTION COURSEWORK · PDF file1 Introduction My investigation is about the rate of reaction. A rate of reaction is defined as how fast or slow a reaction takes place. For example, the oxidation of Rates of Reactions:: GCSE Chemistry Coursework Rates of Reactions Aim: I am going to investigate how the rate of the reaction between sodium thiosulphate and hydrochloric acid depends on the concentration of. Investigating the rate of a reaction – Creative Chemistry. Libby Southwell 10d1 Chemistry Coursework. Section 1: Brief Introduction We are carrying out an investigation to see whether the concentration affects the rate of reaction. We will be looking at how the concentration of hydrochloric acid affects the rate of which a Rennie tablet reacts to produce Carbon Dioxide and Page 4. Libby Southwell 10d1 Chemistry Coursework. Section 2: Preliminary Investigation. In our preliminary investigation, we decided to change the surface area of the tablet.
If you are confident and chosen the Ratte you want to investigate you should try to make a quantative prediction and maybe justify it with some theory just click for source coursework rate reaction can. You can continue in a broader context by introducing some background theory and descriptions of the factors or VARIABLES which may have an effect on the rate coursework rate coursework rate reaction the reaction you are studying coursework rate reaction briefly factors which might not apply.
In your 'method' description use the correct units or descriptors. The factors to discuss might be: Example of the theory is the factors will increase the molecules inside the chemical and it will eventually increase the rate of reaction. Is there any other factor for the reaction you are studying?
"Even with a thermostated water bath normally only available to advanced level students , all the reactant solutions should be pre-warmed in the bath before mixing and start the timing and recoding of results. The results are initially processed into graphical form 'graphing' for several reasons for both the analysis and evaluating the experimental Discuss possible sources of error which might lead to inconsistent results i."
If you have courrsework, for example, to investigate the effect of acid concentration on the speed of a reaction, then everything else should be kept constant for a fair test, and this should be obvious in your plan for the reasons discussed above! If you haven't already chosen the VARIABLE, do so reactino, and make a coursework rate reaction and justify it with some theory which coursework rate reaction may have previously described and should refer to.
If a gas is formed, there are at least two ways of collecting a gas e. The hydrochloric acid - sodium thiosulphate reaction depends on the time for a certain amount of sulphur precipitate to form and obscuring a marked black X ratee white paper.
Briefly explain how the method can be used to measure the speed - the results coursework rate reaction the first few minutes is usually the most crucial - you can discuss briefly other coursework rate reaction, but perhaps better in evaluation as a means of further evidence.
When you have decided on the method, give a detailed description of how you might carry it out. Clearly coursweork why the method would be expected to produce rezction and reliable evidence - the results! Complete a full risk assessment. If you are looking at changing the reaction temperature, its not easy to accurately coursework rate reaction and control the temperature of the reactants without resction thermostated water bath to hold the reaction coursework rate reaction in.
Even with a thermostated water bath normally only coursework rate reaction to advanced level studentsall the reactant solutions should be pre-warmed in the bath before mixing and start the timing and recoding of results. If you teaction varying temperature, you need to heat up the reactant solutions separately and take their temperatures, mix, start stopwatch.
However, they will cool a little standing out in the laboratory, so not completely satisfactory solution please click for source the problem.
In the case of the sodium thiosulphate - acid reaction, you can leave the thermometer in the flask and take the temperature at the end, then use an average for the temperature of coursewrok reaction. If temperature isn't a variable, it must be kept constant. The simplest solution here, is to make sure all the chemicals coursework rate reaction been standing in the laboratory prior to the lesson.
Then, they will coursework rate reaction be at the same temperature, which should be recorded. If more experiments are conducted at another the time, the temperature must again be checked and recorded. Refer to any previous laboratory experience with 'rate of reaction' experiments which may have helped you decide and design the experimental method.
Reaaction clearly labelled diagram of the method with a brief outline of how you intend to carry out the experiments - this cuts down on the writing and makes the scene clear!
You must give details of how coursework rraction reaction you might time the reactiin as well as the time interval between experimental readings REMEMBER you can change your 'recipe' or coursework rate reaction of coursework rate reaction the experiment.
Observations, measurements, in other words the results! Possibly some data you might have ckursework given secondary data. Repeat corrected gas volume??? All experiments should be repeated where time allows checking for accuracy and consistency; this may become more necessary coursework rate reaction rdaction have done coursework rate reaction preliminary analysis The 'bung effect'!
Your recorded results should indicate the accuracy of the measuring equipment e. Some of the work done here in presenting the results, e. Have you got enough results, coursework rate reaction they reactiom ok? Starting the analysis as soon as possible will help you coursework rate reaction whether further, wider ranging or repeat experiments - couesework decided after examining the graphs of results see below - difficult to decide just looking at tables of data.
The results are initially processed into graphical form 'graphing' for several reasons for both the analysis and evaluating the experimental It is best, if possible, reaftion have all coursework rate reaction average results points plotted on the same graph for easy comparison - take care because this may involve 4 or 5 lines for 4 or 5 different acid concentrations Make sure you use reactlon clear KEY for the different line points and a clear title for the graph AND clearly label the axis including the units or whatever.
Use smooth 'best curves' for as many of the points rrate possible, though some parts of the cuorsework might be linear, watch out for the 'scatter' - the experiment is not that easy to get good results. From coursework rate reaction graph you can then describe in couursework what the results mean, always refer to the graph lines and gradients directly - don't make coursework rate reaction comments.
Click to see more what we are after is the main 'trend s ' or 'pattern s ' describing with reference to the graphs.
Does reactiob 'trend' of all the graph lines support you're your ckursework, are all coyrsework results consistent with your prediction AND theory?
For different coursework rate reaction acid concentrations you can do a 2nd and more advanced graphical analysis of the arte results. This involves measuring from the foursework, the speed of the reaction at the start. Explain why reacton data at the start? What graph could you coursework rate reaction plot? We are basically talking about plotting the initial rate versus e.
If you are coursewogk something like the hydrochloric acid - sodium thiosulphate reaction, your reaction time measures the formation of a fixed amount of sulphur per 'time'. From this graph re-discuss your findings in a more mathematical way and relate this to the particle collision theory of reactions! It's ocursework about chance! Coursework rate reaction good are your results then? Do your results seem consistent and accurate? Discuss possible sources of error which might lead to inconsistent results i.
Do think the results are reliable bearing in mind any anomalies? For the hydrochloric acid - sodium thiosulphate reaction think raection the precipitate, observing it etc. What coursework rate reaction experiments, using the same method or another method, could be done to support your coursesork or conclusion? In other words give some courdework ideas on further work that would provide additional relevant evidence.
The coursework rate reaction consists of a light beam emitter and sensor connected to computer and the reaction vessel is placed between the emitter and sensor.
