Talk:Abundance (chemistry)

Is it an established term?
Surely, "in abundance" can be used to explain the reduction of effective reaction order, but if the differentiation between "in abundance" and "in excess" stated in the article is established, why is the latter more frequently used in that very context? Besides, of the eight pages in the article name space that link here, only one, Bjerrum plot, uses the term in the stated sense.

Apart from usage, the differentiation itself shall show up in textbooks. However, the Google-Books search for "order reaction"|"reaction order" "in abundance" "constant"|"not change" "excess" yields only a dozen results, nine of which are in German and do not contain the term. Of the remaining three, two are editions of Thomas M. Devlin's Textbook of Biochemistry, who uses the term in the sense of this article but does not define it, and one uses "abundance" quantitatively ("the difference in abundance"), as does the only source referenced in the article ("arsenic ranks 51st in abundance"); User:PhilKnight inserted it as reference for "in excess", in 2009, together with the moresources tag.

I suggest to delete this article. Bjerrum plot could link to Rate equation. --Rainald62 (talk) 14:37, 13 February 2022 (UTC)
