    Finding the rate law was the overall goal of the laboratory. When finding the wavelength of the Azo Orange II dye‚ the highest wave was the point used‚ 483nm. The plotted points of the different concentrations absorbance’s made sense to have a steady upward slope because the dye was diluted in steady increments from full to ¾ and so on. Beer’s law was used next to calculate the absorbance of they time over time as bleach was added. One the absorbance value was calculated‚ the concentrations were
