Question

How can a spectroscopic measurement be used for rates of reactions?

Answer 1

Yes, Using a Spectrophotometer for example.

Explanation:

The best example of using spectroscopic data to track the reaction rate is using a spectrophotometer, where we can use Beer-Lambert law `A=epsilonxxlxxC` to calculate the concentration of a reactant consumed or a product formed at different time intervals, and therefore, determining the reaction rate.

`Rate=k[Reactant]^n`

Here is a full lab experiment on how to determine the rate of the reaction using a spectrophotometer:
