Suppose you have a box of atomic hydrogen, initially at room temperature and atmospheric pressure. You then raise the temperature, keeping the volume fixed. a) Find an expression for the fraction of the hydrogen that is ionized as a function of temperature. (You'll have to solve a quadratic equation.) Check that your expression has the expected behaviour at very low and very high temperatures. b) At what temperature is exactly half of the hydrogen ionized? c) Would raising the initial...
