\newpage  \subsection{Finding the orders of reactions and k at room temperature}  It is clear from figures 1 and 2 that the experiment to find the order of the reaction with respect to Potassium Iodide has a systematic error. Contributing factors could include the fact that it was difficult to ensure that the solutions mixed together completely. Several experiments had to be repeated due to this. As well as this, the imprecision of the volume of Starch added could have had a greater effect than predicted, as the change in total volume could have had an effect on a rate determining step. However, the lack of such error in the experiment changing the concentration of Potassium Peroxidisulfate would seem to suggest otherwise. It is more likely that the diluted solutions of Potassium Iodide became oxidised, or were incorrectly diluted; this would account for the constant error throughout. If more repeats had been taken, with different concentrations, then a better graph could have been drawn for both experiments; this would be a suggestion if the investigation were to be repeated.  \\\\
