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)
