Recall that entropy is the degree of chaos or disorder of a system and that it depends on the following:

1. Phase: The gas phase has the highest entropy, followed by the liquid, and then the solid phase with the lowest entropy.

Gas > Liquid > Solid

2. Complexity: More elements in the compound leads to higher entropy.

Ex. NO3(g) [4 elements] has higher entropy than NO2(g) [3 elements].

3. Mass: The greater the mass, then the greater the entropy.

Ex. Xe(g) [greater mass] has higher entropy than He(g). ###### Problem Details

For each of the following pairs, predict which substance possesses the larger entropy per mole.

Compare 1 mol of O2(g)  at 300 oC, 0.01 atm and 1 mol of O3(g) at 300 oC, 0.01 atm.
