    hey, can anyone explain to me what e and kT are in:

    exp (-e/kT)

    also what would happen if:
    e>kT
    e<kT
    and e = kT?

    thanks.

    Rep good answer (not worth much anyway though)

    exp(-E/kT) [note capital E] is proportional to the probability of finding a particle with E energy at temperature T.
    That is, if I took a random particle at 300K. There is a exp(-1J/k300k) that it has 1J of energy or more.
    If E = kT then the probability of finding a particle with greater or equal to E energy is 1/e or exp(-1).
    If E>kT then the probabilityof finding a particle with greater or equal to E energy is less than 1/e or exp(-1).
    If E<kT then the probabilityof finding a particle with greater or equal to E energy is more than 1/e or exp(-1).
