Consider the isotopes of oxygen 16O and18O. These form three diatomic molecules:16O16O, 16O18O, and18O18O.
(a) What are the relative average translational kinetic energiesfor these three diatomic molecules at 25â—¦ ?
(b) Describe and compare their Maxwell-Boltzmann speeddistributions, and write the f(v) equation for each.
(c) 16O with isotopic mass 15.994 g/mol is much morecommon than 18O with isotopic mass 17.999 g/mol, so itis safe to neglect 18O18O. You have a mixtureof 16O16O and 16O18Othat is 99.80% 16O16O and would like toenrich it by gaseous diffusion to be 99.98%16O16O. How many gaseous diffusion stages arerequired?
