However the percentage of increases from sixty to eighty is ninety percent and from eighty to one hundred percent concentration is one hundred and sixty three percent. This shows an exponential percentage increase in product production by increasing the substrate concentration. Although not viewed in the practical if further concentrations of substrate were introduced to this experiment it would be expected that the rate of reaction would level off. This levelling off point is known as the point of saturation. Which means that the amount of substrate in the solution now exceeds the number of active sites available for the substrate. This is because the maximum number of reactions are being done instantaneously so any extra substrate has to wait until an active site become available. Reviewing the reaction rate graph it can be noted that for one hundred percent concentration the error bar is indicating a large amount of variability compared to the error bars of other concentrations. These results could be accounted for with regard to physical or human error during the practical examination, for example measuring reaction time to the closest 0.01 of a second rather than 0.1, the disk sticking to the base and the thin girth of the tube hampering disk
