Error?[edit]

This reaction releases −242 kJ/mol of enthalpy (heat):

242 or 572? — Preceding unsigned comment added by 190.134.13.35 (talk) 05:56, 6 October 2014 (UTC)

Factual error[edit]

This was a dispute over the inclusion of N2 in the equation of complete combustion since it doesn't react. It was decided it should be kept since it affects the temperature and does react to make minor species. Full details are in the Combustion Archive.

Improvements needed[edit]

This was a dispute that spawned from confusion over different terminology meaning the same thing, particular adiabatic combustion temperature with adiabatic flame temperature and heat of combustion with heating value. It was decided that a more conscious effort should be made to include multiple terminology but to also to point the terms are equivalent. Full details are in the Combustion Archive.

Away from the basics[edit]

Does anyone understand what characteristic of oxygen makes combustion happen? What is it about reactions with that specific element that makes fire? How does that attribute work which makes it different from any other reaction that is not combustion? I'd appreciate any input. Thank you.

Typo regarding Nitrogen[edit]

In the "Complete vs. incomplete" section:


"Nitrogen does not take part in combustion, but at high temperatures, some nitrogen will be converted to NOx, usually between 1% and 0.002% (2 ppm)."


One of those figures (0.002% and 2 ppm) has to be wrong, because...


0.002% would be 20 ppm.

0.0002% would be 2 ppm.


I would change it myself but I don't know which figure is the correct one, and having no luck searching online.
