Determine initial rate of reaction
WebPurpose: Determine the rate law for the reaction of the dye crystal violet with hydroxide. Reading: Olmstead and Williams, Chemistry , sections 13.3 and 13.4. ... However, since we are studying the initial rate of the reaction, a linear relationship between concentration and time may be assumed. Initial rate WebAug 31, 2024 · To do this, you calculate the slope of the linear standard curve, which is in units of absorbance change/µM PNp. Divide the initial rate (delta absorbance/min) by the slope of the standard curve (delta absorbance/µM) to get µM/min. This can also be written as µmoles/min/liter, which is also units/L.
