Question

1. Why would it be beneficial to slow down the rate of a very fast reaction? Give at least one example of a fast reaction that is slowed down. Provide at least one citation for this question.

2. What does order mean when discussing kinetics? Discuss the difference between zero, first, and second order reactions and how order can be determined for a reaction. Provide at least one citation for this question.

3. Why is it important to start the data collection before placing the cuvette in the spectrometer?

4. If the rate constant is independent of analytical wavelength, why is it still beneficial to use the maximum absorbance wavelength for data collection?

Explanation / Answer

1. A very fast reaction occur in fraction of second. So in order to know the nature of reactants, how much mole of reactant is needed to get say x mole of product, what intermidiate formed between reactant and the final product etc. reactions are slowed down for better understanding. For example, Ice that freezes too quickly is less clear than ice that freezes slowly. Also, corrosion is slowed down by passivating a metal surface.
