suggestions: How about commenting on the autocatalysis in organo-zinc additions? See, for example, the work of Soai. What are the implications on the evolution of the homochiral world? Christian.gampe (talk) 13:19, 24 October 2011 (UTC)Reply

Impressions: The article is reasonably organized, but needs more examples and graphics.

Suggestions:

- Your article has no lead section, which is a paragraph and representative scheme outlining what you are talking about.

- The word "scalemic" comes up a lot, and may be worth defining.

- I suggest redrawing all equations in LaTeX or some other equation editor like MathType (or even equation editor).

- In the section defining both (+) and (-) non-linear effects, you may want to briefly outline the potential causes of both (scalemic catalyst, product, starting material aggregates).

- I would present the ML2 model with a clearer equation showing the equilibrium constant definition. You also seem to be confusing the pre-equilibrium approximation with the steady state approximation. The ensuing discussion is not particularly clear. A concrete example might be better. I understand that the different catalyst aggregates might have different selectivities. But how do I go from that to the final ee? Can you derive the equation in Figure 2? Why is everything assumed to be zero-order in substrate? Alternatively, write out the various kinetic schemes, and run simulations in COPASI to show me what is going on. For example, can you reproduce what's in Figures 9 and 10 in a simulation?

- I like the examples, but you need a few more. Also convert to ChemDraw. Also, as I mentioned before, the Kagan work on the Hajos-Parrish reaction seems to have been refuted.

Non-linear effect or something else? edit

Is it a non-linear effect when there's an abrupt change in a system? For example, landslides, snow or sand avalanches, earthquakes. In these instances there is a build up of tension and then one or more sudden releases. The system's property changes over time are obviously not linear because of the break points but is it "non-linear" in terms of this article? — Preceding unsigned comment added by 2.98.250.157 (talk) 14:31, 4 October 2014 (UTC)Reply
