rate of reaction coursework variables Rates of reaction coursework[preview]. Rates of Reaction Essay - Rates of Reaction Coursework. Introduction. In this piece of science coursework I will be experimenting how the rate of reaction between Sodium thiosulphate and hydrochloric acid is affected by the concentration of Sodium thiosulphate.  There are different variables that can affect the rate of reaction. The different variables include Temperature, catalysts and concentration. In this piece of coursework, I'll be analysing the concentration. The products we get are Sodium Thiosulphate + Hydrochloric Acid --> Sodium Chloride + Water + Sulphur dioxide Na2S2O3 (aq) + 2HCl (aq)--> 2NaCl (aq) + H2O (l) + SO2 (g) + S (s) Apparatus = 1 Eye protection 2 measuring cylinders 1 White paper with bold black cross [tags: Papers]. Rates of Reaction Coursework Prediction (Na2 S2 O3 + 2HCL > 2NaCl + SO2 + S + H2O) This is the equation for Sodium Thiosulphate reacting with 2 Molar of Hydrochloric Acid. There are a number of variables in the experiment which must be controlled in order for the experiment to be a fair test. These include temperature, which must be kept constant throughout the experiment or the results would not match. The experiment will be performed at room temperature (Around 25 degrees). Another variable is volume of Hydrochloric acid, which must be kept the same as well. For this experiment, I will. 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.

In order to get maximum marks in this coursework it is vital that you discuss all factors which affect the rate of a reaction. First, you can start by describing the reaction situation you are intending to investigate. For example, with the word and symbol equation, short description about the reaction, and so on. This sets the scene. If you are confident and chosen the VARIABLE you want to investigate or should try to make a quantative prediction and maybe justify it variabes some theory if you 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 of the reaction you are studying include briefly factors which might not raction. 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 coursewirk will eventually increase the rate of reaction.

Is there any other rate of reaction coursework variables for the reaction you are studying? Rate of reaction coursework variables you have decided, 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 now, and make rate of reaction coursework variables prediction and justify it with some theory which you 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 on white paper.

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

However, they will cover letter for call center operations manager a little standing out in rate of reaction coursework variables laboratory, so not completely satisfactory solution to 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 the reaction. If temperature isn't a variable, it must be kept constant. The simplest solution here, is to make sure all the chemicals have been standing in the laboratory prior to the lesson.

Then, they will all 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. A 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 long reactipn might time the experiment as well as the time interval between experimental readings REMEMBER you can change your 'recipe' or way of doing the experiment. Observations, measurements, in other words the results! Possibly some data you might have been given rate of reaction coursework variables data.

Determining Reaction Rates. The rate of a reaction is expressed three ways: The average rate of reaction. The instantaneous rate of reaction. The initial rate of reaction. Determining the Average Rate from Change in Concentration over a Time Period. We calculate the average rate of a reaction over a time interval by dividing the change in concentration over that time period by the time interval. For the change in concentration of a reactant, the equation, where the brackets mean "concentration of", is. Note: We use the minus sign before the ratio in the previous equation because a ra. $5/page. Registration is required.

Starting the analysis as soon as possible will help you decide whether further, wider ranging or repeat experiments - best decided after rate of reaction coursework variables the graphs of results see below - difficult to decide just looking at tables of http://keiba-online.info/3/n-31-1.php. The rate of reaction coursework variables raet initially processed into graphical form 'graphing' for several reasons for both the analysis and evaluating the experimental It is best, if possible, to have all the average results points plotted on the same graph for easy comparison - take care because this may involve 4 or 5 lines rate of reaction coursework variables 4 or 5 different acid concentrations Make sure you use a clear KEY for the different line points and a clear title variablles the graph AND clearly label the axis including the units or whatever.

Use smooth 'best curves' for as many of the points as possible, though some parts of the graph might be linear, watch out for the 'scatter' - the experiment is not that easy to get good results. From the graph you can then describe in words what the results mean, always refer to the graph lines and click at this page directly - don't make vague comments.

So what we are after is the main 'trend s ' or 'pattern s ' describing with reference to the graphs. Does the 'trend' of all the graph lines support you're your prediction, are all the results consistent with your prediction AND theory? For different the acid concentrations you can do a 2nd and more advanced graphical analysis of the limestone results.

This involves measuring from the graph, the speed of the reaction at the start. Explain why best data at the start? What graph could you then plot? We are basically talking about plotting the initial rate versus e. If you are doing something like the hydrochloric acid - sodium thiosulphate rate of reaction coursework variables, 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 ratd theory of reactions!

It's all about chance! How variwbles 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 rate of reaction coursework variables the precipitate, observing it etc. What further experiments, using reactiin same method or another method, could be done to support your prediction or conclusion? In other words give some detailed ideas on further work that would provide additional relevant evidence.

The system consists of a light beam rate of reaction coursework variables and sensor connected to computer and the reaction vessel is placed between the emitter and sensor. The light reading falls as the sulphur precipitate forms. On the rate of reaction coursework variables gas calculations page, temperature sources of error and their correction are discussed in calculation example Q4b.
