We are basically talking about plotting the initial rate versus e. I will know when the reaction is taking place as the solution turns from clear to opaque. Papers essay about rate of reaction of dilute hydrochloric acid and sodium thiosulphate - rate of reaction of dilute hydrochloric acid and sodium thiosulphate to investigate the change in rate of reaction between dilute hydrochloric acid and sodium thiosulphate as the concentration varies.

First, you can start by describing the reaction situation you are intending to  investigate e. 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. From the graph you can then describe in words what the results mean, always refer to the graph lines and gradients directly - dont make vague comments.

Refer to any previous laboratory experience with rate of reaction experiments which may have helped you decide and design the experimental method. 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. Some of the work done here in presenting the results, e. All experiments should be repeated where time allows to check for accuracy and consistency, this may become more necessary after you have done a preliminary analysis the bung effect! - look up about dead volumes and its correction when dealing with gas volumes! Your recorded results should indicate the accuracy of the measuring equipment e.

    chemistry gcse coursework rates reaction conclusion

    Background information the collision theory briefly for a reaction to occur particles have to collide with each other. On the other hand, a reaction which takes a longer time is known as a slow reaction, and as a result is known to have a low rate of reaction. Include details of the amounts of chemicals you might use mass, volumes, dilutions units etc.

    The reaction that takes place is as follows - sodium hydrochloric à sulphur sulphur sodium water thiosulphate acid dioxide chloride na s o 2hcl à s so 2nacl h o ------------------------------------ the reactio. 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. And how could the method be improved to minimise these sources of error.

    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. A certain amount of energy is needed to allow a reaction to take place. Your write-up must be your work produced from your study and your experiments.
