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??

To determine the statements that are true for the standard entropy change for the conversion of ozone to oxygen, we need to consider the factors that affect entropy change: molecular factors and stoichiometric factors.
Molecular factors refer to the number and arrangement of atoms in molecules. Generally, when a substance goes from a more complex or ordered structure to a simpler or less ordered structure, the entropy tends to increase. So, molecular factors predict an increase in entropy rather than a decrease.
On the other hand, stoichiometric factors consider the balanced chemical equation and the number of moles of reactants and products. It accounts for changes in the number of particles during a reaction. If the overall number of particles or moles increases, there is generally an increase in entropy; if the overall number of particles or moles decreases, there is generally a decrease in entropy.
Based on this explanation, statement 1 ("Molecular factors predict an increase in entropy") is true, as it correctly describes that molecular factors predict an increase in entropy.
Statement 6 ("Stoichiometric factors predict an increase in entropy") is incorrect because, in the conversion of ozone to oxygen, the stoichiometric factor predicts a decrease in entropy. This is because the reaction involves the decomposition of ozone (O3) into oxygen (O2), resulting in a decrease in the number of molecules or moles of gas particles.
Therefore, the correct answer is only statement 1. The other statements are not true or do not accurately describe the standard entropy change for the conversion of ozone to oxygen.
