Question

Which of the following statements is correct about $\text{O}_2$ and $\text{O}_3$ molecule?

• A. $\text{O}_2$ and $\text{O}_3$ are paramagnetic
• B. The enthalpy change during the formation of $\text{O}_3$ from $\text{O}_2$ is positive
• C. The entropy change in the formation of $\text{O}_3$ from $\text{O}_2$ is positive
• D. $\text{O}_3$ is more stable than $\text{O}_2$

Hint:

Ozone formation requires energy (like UV light), so it is endothermic (+$\Delta H$).

Answer 1

The Correct Option is B
