Container A is filled with 1.0 mol of the atoms of an ideal monatomic gas. Container B has 1.0 mol of atoms bound together as diatomic molecules that are not vibrationally active. Container C has 1.0 mol of atoms bound together as diatomic molecules that are vibrationally active.

How do you determine which has the least entropy and which has the most?

Container a has the least because it contains monatomic atoms and container c has the most entropy because it contains diatomic molecules that are active. Entropy is essentially the disorder of the system so if you consider all 3 containers, container a will has the least disorder because it only has monatomic atoms. Container b will have the second most entropy because it has diatomic atoms, but they are not moving. The container c has the most entropy because it has diatomic atoms that are moving so it is the most disordered.

The book says container A has the most entropy, then C, then B.
