This proved that the decomposition of hydrogen iodide reaction is a 2nd order reaction. Connect the graphs with the following: The maximum number of enzyme sites are occupied, which is itself a constant at constant enzyme concentration. The graph on the left illustrates the initial rate method for the formation of product. Most of these weeks I have done 8 – 5. So simplified rate data questions and their solutions avoiding graphical analysis are given below.

Powers of 1 are not shown by mathematical convention. You may need to use aqueous ethanol as a solvent since the halogenoalkane is insoluble in water and a large volume of reactants, so that sample aliquot’s can be pipetted at regular time intervals. Simple exemplar rates questions to derive rate expressions. I’ve also shown how to calculate the rate constant. Have your say about doc b’s website. You can think the other way round i. In reality the results would be not this perfect and you would calculate k for each set of results and quote the average!

The third graph is a plot of HI decomposition rate versus [HI] squared, and, proved to linear – the blue data line was pretty coincident with a black ‘best straight line’.

An individual order of reaction is the power to which the concentration term is raised in the rate expression. News and current affairs Replies: Reaction between iodine and propanone coursework Propanone – no change 5.

Because the conductivity of a solution depends on the concentration of the ions, it is a good idea to calculate the molar conductivity.

Is it too soon to be excited about Christmas. This technique will be used to calculate the order of the reaction between iodine and propanone. By the way, this makes it look as if wrong as I said I might be! The oxidation of iodide to iodine by potassium peroxodisulfate can be followed by a method known as the ‘ iodine clock ‘. The last 3 weeks have been an absolute waste of time.
