### 4G. 3 7th edition

How do I go about this question: Which would have higher molar entropy at T=0, single crystal of BF3 or single crystal of COF2

This question was recently answered in the same topic, but the answer is that the degeneracy of COF2 allows for a greater disorder and more possible arrangements of atoms, compared to BF3 since there is only one arrangement for that. Since there is higher degeneracy is COF2, it has a higher molar entropy and degeneracy is more powerful than mass concerning molar entropy.
