Rose, I think you're on the right track but some pictures or schemes would be helpful. Christian.gampe (talk) 13:06, 24 October 2011 (UTC)[reply]

Comments:

This article is well on its way. It just needs more pictures and examples.

Suggestions:

- your lead section could use a concrete example of a reaction scheme like a Heck reaction - a graphic would also be useful for explaining the difference between traditional tactics and RPK

- The distinction between integral and differential measurements is not that clear. Instead of saying "polynomial fit to the experimental curve," say that the direct observable is concentration vs. time, and that can be numerically differentiated to give rate vs. concentration. Polynomials are one way to do it, but are not the only or even best way to do it.

- Having a discussion of how to read rate vs. concentration graphs might be useful.

- Avoid in-line equations--write out the equation in Equation Editor and copy and paste a graphic, or use some other favorite method.

- Same excess: Some concrete examples of catalyst activation, deactivation, and product inhibition would be useful. In addition, I think a table showing reagent and product concentrations over the course of a reaction, followed by side-by-side comparison with a reaction started from "in the middle" would be a clear way to explain the experiment.

- Difference excess: My pedagogical insight about this is as follows. Suppose you have a catalytic cycle with rate constants k1, k-1, and k2, and you want to extract these from the data. You could run the reaction starting from some [A]0 and [B]0. With different time points over the progress of the reaction, you can get rate vs [A] and [B]. Why aren't three data points enough to extract the rate constants? Because [A] and [B] are not independent. Specifically, [A]-[B]=excess. Therefore, you need different points from reactions with different excesses.
