my question is this

what fraction of CO2 molecules have a kinetic energy between 1.0eV - 1.1eV at 1000k

on the problem set it says to use the maxwell distribution of speeds, but there is no way this can work for kinetic engery, if it was velocity its easy,

i mean the formula for maxwell is this

f(v) =4pi(M/2piRT)3/2*v^2 e-^(Mv^2/3RT)

but just dont see where kinetic energy fits in this equation
