**The question**
Using the Maxwell-Boltzmann speed distribution, determine the fraction of
nitrogen molecules at 298 K that are moving with sucient energy to break a hydrogen bond
between two water molecules existing as a "dimer" in the gas phase. You will have to figure
out what the strength of the bond is (by googling or otherwise) and also learn about, and
use, something called the "error function" to solve this problem. After figuring all of this
out, determine what fraction of N2 molecules can break the bond at 2000 K.
**equation**
**Attempts at this problem***
I found the strength of a N2 bond to be 38.4 Kcal or 945.33 KJ/mol
The mass of N2 is = 28/avogadro's # = 4.6 x 10^{-23} g = 4.6 x 10^{-26} kg
K=1.38 x 10^{-23}
T=298
The real problem that I am having is figuring out how to solve the error function and how to find t. I do know that the equation for average <v>=(8KT/pi*m)^1/2 .
