Among the following statements which one is the only correct one a. The rotational partition function calculated as T/0a is not in error for heavy molecules at high temperatures The translational partition function can be calculated analytically because the spacing of the translational energy levels is typically greater than KT The contribution to the total entropy from vibrational modes can be assumed to be small for a molecule such as buthanol d. none of the other answers The translational partition function is relevant only for monoatomic gases b. C. e.

For all three of your assigned systems (Ne, Oxygen, Nitrous oxide), calculate the complete partition function (assuming a perfect gas) at T, = 2.00 and e, = 0.0500. Information on the symmetry number for your polyatomic molecules is posted in a table under the Reference section in the Content Library The symmetry number for rotational partition functions. Homonuclear diatomics: o=2 Heteronuclear diatomics: o=1 Polyatomics: Name Nitrous oxide 1

How?
