Final 2011 1C

Which has greater residual entropy at 0K: NO or BF3

Why does NO have a greater residual entropy at 0K?

NO has greater residual entropy because its two atoms can result in the arrangement of two different molecules. It can either be NO or ON. However, the BF3 molecule only has one way it can be arranged. This is related to Boltzmann's formula for calculating residual entropy.
