Question

Imagine a particle that can exist in only 3 states or levels.  These energies levels are –0.1 eV, 0.0 eV, and +0.1  eV.  This particle is in eq with a reservoir at T = 300 K.

A) Find the partition function for this particle.  I want a number and a unit.  Comment on what you would expect, and what the partition function tells you!    

B) Find the relative probability (%) for the particle to be in each of these states.  Hint:  Verify that these 3 percentages add to 100% in both parts b and c.

C) Now adjust the energy-zero reference point, so that the lowest energy is at 0.0 eV and the next states are therefore at + 0.1 eV and + 0.20 eV.  Repeat parts “a” and “b” above using these new energies, and comment on the results.
