For a reaction to occur, particles must collide. Internet, and of course your class work and exercise books and mention your research sources in your coursework report and quote your research sources  and any previous rates experiences any previous rates of reaction experience is invaluable and can be usedquoted in your write-up - particularly knowledge of experimental methods which can count as preliminary work. Below is the reaction equation sodium hydrochloric sodium water sulphur sulphur thiosulphate acid chloride dioxide na2s2o3 (aq) 2hcl (aq) 2nacl (aq) h2o(l) so2(g) s(s) prediction i predict that as the concentration of sodium thiosulphate decreases, the reaction t.

A brainstorm on rates of reaction for chemistry coursework investigations-projects ideas for coursework assignments or projects involving the rates or speed of chemical reactions and is a companion page to detailed gcse revision notes on the factors affecting the rates of chemicals which also has brief descriptions of experimental methods and equations, particle pictures and fully explains all the factors affecting the rate of a chemical reaction advanced level chemistry theory pages for gceasa2ib and adventurous gcse students! Aim for a high investigation-project mark - you have nothing to lose for your assessment! But you can use and extend these brain stormed ideas to most rates of reaction coursework assignments the magnesiumzinc acid reaction, you can investigate acid concentration and amount of metal and the zinc reaction is catalysed by copper and other ions in the acid) decomposing hydrogen peroxide with a solid catalyst or soluble transition metal compound. Collision theory reaction rates essays - the rate of a reaction between hydrochloric acid and sodium thiosulphate aim i am going to investigate the effect of changing the concentration of sodium thiosulphate on the rate of the reaction between hydrochloric acid and sodium thiosulphate. Your teacher will have a good idea what to expect and you must be able to justify all your write-up , neither do i replace your teacher supervisor! However i sometimes get really interesting questions and learn something new myself - and thats always a pleasure! A brainstorm outline of a whole investigation is outlined below, it is not meant to be prescriptive, but can form the basis of aiming for a high mark and hopefully give you plenty of ideas.

When you have decided on the method, give a detailed description of how you might carry it out. Papers - investigating factors that affect the rate of a reaction aim to investigate the rate of reaction when you combine the chemicals sodium thiosulphate and hydrochloric acid at different temperatures. I believe that when the most concentrated solution is used the reaction would be at its fastest. For sources and references you should research rates of reaction for theory, experimental methods etc.

    E evaluating - and how good are your results then? Error sources? Can we improve the existing method? Are there other experimental methods? Do your results seem consistent and accurate - always refer directly to the graph or graphs in your analysis. More marks are lost by not writing things down, than by not doing experiments! Your write-up must be your work produced from your study and your experiments. And how could the method be improved to minimise these sources of error.

    So what we are after is the main trend(s) or pattern(s) describing with reference to the graphs. If temperature isnt a variable, it must be kept constant. 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.

    In your method description use the correct units or descriptors. However, they will cool a little standing out in the laboratory, so not completely satisfactory solution to the problem. If you are confident and chosen the variable you want to investigate you should try to make a prediction and maybe justify it with some theory if you can. Include details of the amounts of chemicals you might use mass, volumes, dilutions units etc.
