What are the most probable populations of the first several
vibrational levels of O2(g) at 1000 K? The
characteristic vibrational temperature is 2274 K.
Consider the first order reaction 2 N2O(g) ⟶ 2 N2 (g) + O2(g).
What will [N2O] be after 3 half lives when 0.25
moles N2O is placed in a 1.00-L reaction vessel?
1. Determine the ratio of populations in the lowest and first
excited energy levels, Po/P1, for the indicated systems at two
temperatures, 50 K and 298 K: a) The 1700 cm−1 stretching mode for
the carbonyl group in the peptide bond of a polypeptide b) the 150
cm−1 torsional mode for the C=C bond in trans-2-butadiene

In
most every society there exists segmentation, usually on several
levels. What about class, ethnic realities and “race” causes people
in our society to speak differently from so-called main-stream
English? What do linguistic distinctions tell us about the social
reality?
