Ok - Physics question.

Nitrogen molecules are at 1773K. Room pressure. 1 mole.

The ionisation energies of nitrogen are as follows (in Kj/mol)
1st 1402.3
2nd 2856
3rd 4578.1
4th 7475.0
5th 9444.9
6th 53266.6
7th 64360

What ionisation energy number are these molecules in? Ive tried using E=Mc(change in)T and E=nkT… no joy… hopelessly small…
Any help… please…?

OK - found a work-around to the issue.
Using E=nkT, the energy of the nitrogen is much much lower (as an average). However this is only an average and using a distribution curve some of the atoms in the molecule may have sufficient energy to become ionized…
least i hope thats right…
