I am working on a Boltzmann equation question and I know that the solution I am looking for is that:

log(n

_{ij}/n

_{ji})=log(g

_{ij}/g

_{ji})-E

_{ij}(eV)(5040/T)

The only thing I don't understand is why log(e

^{-Eij/kt}) = θ = 5040/T

From what I have read in textbooks, it is just a given, but I really want to know why!

Any help gratefully received!

Thank you
