Hi everyone!
For a retake exam of Molecular Physical Chemistry I have to solve the next exercise:
Calculate the degree of dissociation of the OH radical at 5000K. Is ionisation an issue at these energies?
For dissociation I have OH* -> O + H, and for ionisation OH* -> OH+ + e-.
To start with, is this correct?
I know how to solve this exercise, you basicly have to formulate an equilibrium constant K, with a translational, electronical, rotational and vibrational contribution.
For the dissociation I get a logical value for K and the degree of dissociation alpha I calculated from K, so I believe my way of working is correct, but the my problem is, for the ionisation reaction, I can't find any values in the CCCDCB database for the characteristic rotational and vibrational temperature for OH+ (I can only find values for OH), and no energy levels either to calculate Kel.
Does anyone have any idea of how to solve this problem?
Maybe OH+ and OH have the same θvib and θrot? But I'm not sure if this is correct?
Thanks in advance!
