Appearance... Is it really brown?  I seem to remember an experiment where 2 NO2 <->N2O4 via a change in pressure or temperature; and the glass vessel being a brown shade when in the NO2 form and clear when in the N2O4 form.  It is this constant equilibrium between the two gases that make N2O4 appear brown, when really its the NO2 that is brown.

message: The data for NO2 and N2O4 are not very consistent in literature, probably because they always exist together in equilibrium.  Verification of the data is recommended before use. R6144 14:54, 26 August 2005 (UTC)

message: Disclaimer: I am *so* not a professional chemist, but from the article:
"Higher temperatures push the equilibrium towards nitrogen dioxide."
That doesn't seem right... why would higher pressures tilt the equilibrium toward twice as many molecules? In most cases that I am familiar with, increasing pressure on a gas favors the smaller number of molecules.

ΔG can be calculated at any temperature, and it has been done  using known values for ΔH and ΔS. Where ΔG is negative, the reaction is spontaneous, whereas if ΔG is positive, the reaction is not. That's the quick answer. --Rifleman 82 (talk) 03:41, 6 December 2011 (UTC)

message: In the graphic, the yellow part of the diamond displays a zero, indicating 'un-reactive', despite that fact in the table above, the chemical is mentioned as reacting with water. Plus, since it IS a rocket fuel, one would expect it to be reactive.Mr Morden76 (talk) 21:33, 29 July 2013 (UTC)

message: Nitrogen tetroxide is a very aggressive oxidant, and as such requires great handling precautions. I have read (but cannot confirm) that nitrogen tetroxide spilt on the skin will immediately and violently react with and oxidise subcutaneous fat, so violently that it can spontaneously burst into flame. 2001:8003:E40F:9601:645D:C915:B2CA:4B75 (talk) 23:13, 7 December 2023 (UTC)
