Reaction mechanism, formation of acid rain?
Posted 15 March 2007 - 05:22 PM
so far this is what i have:
1. O + N≡N → N=O + N
2. N + O=O → O + N=O
3. 2N=O + O=O → 2O=N=O
4. N=O + O=O=O → O=O + O=N=O
5. O=N=O + O-H → H=O=N=O
I know that electrons from the triple bond of the nitrogen in step 1 move to one N atom and this means that the O is attracted to the other N and they form NO.
I can also complete number 2 (i think) as it is the same as above, with different compounds. It's number 3 onwards that cause the problems.
any help appreciated!

The structure of ozone is not O=O=O, it only can be described by means of resonance structures. The mechanism for reaction of NO with O3 is quite similar to that for reaction between NO and O2.
In the latter mechanism, nitric acid is formed, but the OH-group attaches to the N-atom through a single bond, so no H=O=N(=O)=O, but H-O-N(=O)=O.

Thank you very much for the above explanation - I think I'm getting there with understanding!!

In answer to your question; I'm pretty sure ozone is represented as O=O-O
hope this helps!

and then how that reacts with H2O to form HNO3(aq) + NO(g)
you might also want to include how nitric acid is formed, with the OH-group attaching to the N-atom through a single bond, H-O-N(=O)=O
it all balances quite neatly.......honest
anyway, good luck guys

i know i dont have much time left to finish this but im not at all motivated, and i have physics coursework as well.. ahhh! on top of that i have to go to cambridge uni for 2 days, i have no chance! haha
good luck everyone!

: + O=N
Radicals, being at the top and bottom of this, that is going into Degree level chem. FUN!!! Hope this helps!! Good luck!!!

this information was from the "Salters Advanced Chemistry Chemical Storylines" book
hope this answers your question.

over the word limit tho, just wondering do sub headings count?
and if you put something like "Fig 3. lambda sensors balance the mixture etc etc" under a picture would that count?
probably a stupid question but hey =)
loads of people in my chem class said "JO! i saw your post on that forum! =O" haha ace

as far as i know..figure quotes/notations are not counted and also bibliography ..im not sure abt sub headings..but i think u do count them??!![/COLOR]

when i first read the question i thought it was about box 2 on page 4, but then i saw it said atmospheric nitrogen
so are they asking how acid rain is formed even when there arent any car emissions??
