Talk:Thermodynamic versus kinetic reaction control

title change

This article needs to be changed to "Thermodynamic versus Kinetic reaction control" -- having "kinetic reaction control" redirect to "thermodynamic reaction control" makes no sense. That's like calling an article about acids and bases "acids," and having "bases" redirect to it. -216.145.255.2 18:24, 12 March 2007 (UTC)Reply


substantial editing

edit

I've taken the liberty to considerably expand the descriptive portion, as well as correct some errors in English. Illustrations of the other examples may in future be added.

In the introductory paragraphs, it is stated that "Differentiating between thermodynamic reaction control and kinetic reaction control ... determines the final composition of the reaction product mixture ...". This is a bit awkward, as a FINAL product always is a thermodynamically controlled product? —Preceding unsigned comment added by Beeftink (talkcontribs) 07:37, 26 July 2010 (UTC)Reply

This page needs more information

edit

Just taking a quick look, but this page does not talk about coordinates or stabilities very much, nor does it show free energy diagrams which would help people understand how coordinate control would be prefered once activation has been achieved opposed to random collision energy. — Preceding unsigned comment added by 132.205.55.181 (talk) 14:41, 12 October 2011 (UTC)Reply

Added selectivity

edit

I edited selectivity to also point to a general, not just stereo kind of selectivity. I hope this was correct. 178.38.76.37 (talk) 16:52, 2 April 2015 (UTC)Reply

Fundamental definition lacking

edit

In the first sentence of the lede, the terms "thermodynamic control" and "kinetic control" are not defined, only contrasted or commented upon. Nor are they defined later. Instead, they are obliquely re-characterized several times in the introduction, in different grammatical constructions and applying to different things: the reaction, the pathway, the parameters. It is a quagmire of metonymy.

I can guess that "thermodynamic control" means "the thermodynamically stable product is in the majority", but this is never stated.

But it could mean something else -- something roughly associated to, but not equivalent to, what I said. In particular, the word "control" is confusing: it seems to refer to the method or intention of a control process, rather than the numerical ratio of the products (i.e. the selectivity).

Are there cases where the changing parameters (pressure, temperature, other chemicals) change the identity of the thermodynamically stable product? How are the terms used then? Do they switch places and what entity do they attach to?
