However, they will cool a little standing out in the 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. 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. 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! Observations, measurements, in other words the results! Possibly some data you might have been given secondary data.
Repeat corrected gas volume??? 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, do they seem ok? Starting the analysis as soon as possible will help you decide whether further, wider ranging or repeat experiments - best decided after examining the graphs of results see below - difficult to decide just looking at tables of data.
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 for 4 or 5 different acid concentrations Make sure you use a clear KEY for the different line points and a clear title for the graph AND clearly label the axis including the units or whatever..
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.
From this graph re-discuss your findings in a more mathematical way and relate this to the particle collision theory of reactions! How 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 about the precipitate, observing it etc.
What further experiments, using the 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 emitter and sensor connected to computer and the reaction vessel is placed between the emitter and sensor.

The rate of a chemical reaction is a measure of how fast the reaction takes place. It is important to remember that a rapid reaction is completed in a short period of time. An example of a fast reaction is an explosion, and an example of a slow reaction is rusting/5(2). For the hydrochloric acid - sodium thiosulphate reaction you can plot either (i) reaction time, or (ii) 1/time versus a concentration or temperature (1/time = relative rate of reaction).
