Degeneracy

What exactly is degeneracy and how does it relate to entropy?

Degeneracy (W) is just the number of ways of achieving a given energy state. Thus, entropy is defined using the equation S=klnW.

Degeneracy, also known as W, is the number of ways you can rearrange a molecule. You can find this by drawing the lewis structure of the molecule in question and see how many ways you can draw the structure. Depending on whether the problem specifies if they want you to find the residual entropy of "_ moles" or "_ atoms" of said molecule, you'll solve for W accordingly. Once you find W, you'll use that number to solve the residual entropy, S=Kb*ln(W).
