can use and extend these 'brain stormed' ideas to most rates of reaction coursework assignments e.g. The magnesium/zinc + 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. Enzyme catalysed reactions e.g. decomposition of hydrogen peroxide solution by catalase (can tricky at GCSE level). The sodium thiosulphate-hydrochloric acid reaction, you can investigate the effects of temperature and concentration. (as far as I know sulphur formation is only catalysed acid) and these reactions get a mention here and there and don't forget to pre-study the rates of reaction revision notes, lots of theory and descriptions of experimental methods and graphs etc. WARNING: Your write-up must be your work produced from your study and your experiments. This web page is meant to teach you how to tackle an coursework e.g. on rates, it is not meant to be copied and the details filled in! Your coursework write-up must expressed in your language and expressed at 'your scientific level'. Your teacher will have a good idea what to expect and you must be able to justify all your write-up. Use the sources/references mentioned below and clearly indicate them in your write-up. More marks are lost by not writing things down, than by not doing experime...
