The question is: What statements are true for the standard entropy change for the conversion of ozone to oxygen?
The choices to pick from are:
1. Molecular factors predict an increase in entropy
2. Stoichiometric factors predict a decrease in entropy.
3. Molecular factors predict a decrease in entropy.
4. If the overall entropy increases, stoichiometric factors are dominant.
5. If the overall entropy increases, molecular factors are dominant.
6. Stoichiometric factors predict an increase in entropy.

Would it be 1 and 6??

  1. 6 definitely is true. I don't know what molecular choices they are talking about so I don't know about that.

  4. Entropy decreases.becoz 1more oxygen atom is added into O2 gas so compactly arrange and randomness decreases.
