Chemistry

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?
