a) At normal pressure and temerature (1 atmosphere, 273 K) and hence D approximatly = 3 nm, what is the largest possible n for which you would expect to observe good agreement with the Bohr Theory?
b) If one reduced the pressure to 1/1000 atmosphere (keeping temperature fixed at 273 K), what would be the largest n? Recall from the homework problem that the spacing D is proportional to (pressure)^(-1/3)
c) In the lab, hydrogen atoms with n approximatly = 100 have been produced. What must be the pressure in these experiments?
