Entropy

[Katherine Jordak 1H]

How does being vibrationally active affect entropy? Why is there a difference in entropy for diatomic and monoatomic molecules and which one typically has more entropy?

[Peri Bingham 1G]

Being more vibrationally active causes a larger value of entropy. The larger or more complex the molecule, the larger the vibrational activity.

[Abigail Yap 2K]

The vibrational motion causes disorder, so entropy increases. Diatomic molecules would cause greater entropy because the dissolution of polyatomic molecules results in a greater number of particles than the dissolution of monatomic molecules.

[Nathan Tu 2C]

Increase in vibrations increases entropy because it increases the possible states that the individual atom can have.

Vibration causes disorder which means an increase in entropy. Diatomic molecules would have greater entropy because the more complex the molecule the more entropy there is.

[Yang Chen 2E]

Are we supposed to know how many energy states a "unit" of vibrational energy adds on?

[Ya Gao]

Diatomic atoms have more entropy than monatomic molecules because there are more possible states to be occupied and the rotational and vibrational energy contribute to the greater entropy.
