Talk:Extent of reaction

Negative Extents of Reaction

The extent of reaction can be negative. There is a common misconception this can never happen. If in the case of A ⇌ B the reaction starts with 0 moles of A and 1 mole of B, the extent of the reaction will range from [0,-1] moles. I think that this should be addressed in the article as there are many confused people out there (including many who have published incorrect papers in scientific journals).

Having just done some reading, I see your point. Although I personally always define this quantity so that it's always positive, there are contexts where it's not even the best choice to do that. I'll have a look at improving this aspect of the article. Good job pointing that out. KeeYou Flib (talk) 18:50, 9 July 2021 (UTC)[reply]

I've made an edit which mentions this, along with a reference. KeeYou Flib (talk) 19:36, 10 July 2021 (UTC)[reply]

References

In the references the work "Atkins, Peter; de Paula, Julio (2006). Physical chemistry (8 ed.). p. 201. ISBN 0-7167-8759-8." is shown twice. I don't know whether this corresponds to Wikipedia's citation style. Also, the fact that they refer to the same page looks suspicious, and could be verified. — Preceding unsigned comment added by 94.169.138.64 (talk) 05:22, 19 November 2012 (UTC)[reply]

This seems to have been addressed. KeeYou Flib (talk) 19:36, 10 July 2021 (UTC)[reply]
