Would it be 1 and 6??
The statements that are true for the standard entropy change for the conversion of ozone to oxygen are:
1. Molecular factors predict an increase in entropy.
2. If the overall entropy increases, molecular factors are dominant.
To determine which statements are true for the standard entropy change for the conversion of ozone to oxygen, we need to consider the molecular and stoichiometric factors. Here's an explanation of each statement:
1. Molecular factors predict an increase in entropy: This statement is false. Molecular factors usually predict a decrease in entropy. In this case, the conversion of ozone (O3) to oxygen (O2) involves a decrease in the number of molecules, which typically correlates with a decrease in entropy.
2. Stoichiometric factors predict a decrease in entropy: This statement is true. Stoichiometric factors consider the change in the number of moles of reactants and products. In this reaction, the stoichiometric factor is positive (+3), indicating an increase in the number of moles of oxygen gas (O2) produced. Since an increase in moles usually corresponds to an increase in entropy, stoichiometric factors predict an increase in entropy.
3. Molecular factors predict a decrease in entropy: This statement is true. As mentioned earlier, molecular factors typically indicate a decrease in entropy. In this reaction, the number of molecules decreases from two ozone molecules (2 O3) to three oxygen molecules (3 O2), resulting in a decrease in entropy.
4. If the overall entropy increases, stoichiometric factors are dominant: This statement is true. If the overall entropy of a reaction increases, it indicates that the increase in moles of products (as predicted by stoichiometric factors) overpowers the decrease in entropy caused by molecular factors.
5. If the overall entropy increases, molecular factors are dominant: This statement is false. If the overall entropy increases, it means that the increase in moles of products (as predicted by stoichiometric factors) dominates over the decrease in entropy caused by molecular factors. Therefore, stoichiometric factors are dominant, not molecular factors.
6. Stoichiometric factors predict an increase in entropy: This statement is false. Stoichiometric factors predict a decrease in entropy in this particular reaction, as explained earlier.
Based on the explanations provided, the true statements for the standard entropy change for the conversion of ozone to oxygen are:
- Stoichiometric factors predict a decrease in entropy.
- If the overall entropy increases, stoichiometric factors are dominant.
