Derivation of Energy Ratio Between
and

where f(ε,T) de is the fraction of molecules with kinetic energies between ε and (ε+dε). We could further multiply and divide by kBT
Recalling
By letting , we could have put the distribution in dimensionless form
f(X,T) dX is the fraction of molecules that have energy
ratios between and
