Question
We discussed in class (several times) how the Boltzmann distribution can
be used to relate the relative populations of two states differing in energy
by AU. Suppose you are given a vial containing a solution of glucose in
water (don't ask why this would happen). For the purpose of this question,
glucose exists in one of two conformations-"chair" or "boat"-with an
energy difference (AU) of 25.11 kJ mol1 between them.
1. What would be the proportion of molecules in the "boat"
conformation at 310K?
2. Thinking back to our discussion of the individual sources of energy
that go into the potential energy calculation for a molecule (e.g. Upond
Uangle, Uelectrostatic. etc), give a plausible explanation of why the "boat"
conformation is less stable.
