Question
**Title: Calculating the Equilibrium Constant \( K_p \) for a Reaction**

---

**Instructions:**

Write the expression for the equilibrium constant \( K_p \) for the following reaction.

- Enclose pressures in parentheses and do not write the chemical formula as a subscript. For example, enter \( (P_{\text{NH}_3})^2 \) instead of \( P_{\text{NH}_3}^2 \).
- If either the numerator or denominator is 1, please enter 1.

**Chemical Reaction:**

\[ 3 \text{PbO}_2 (s) \rightarrow \text{Pb}_3\text{O}_4 (s) + \text{O}_2 (g) \]

**Input Box:**

There is an input box provided to enter the expression for \( K_p \).

**Symbols Available:**

- Common Symbols: \( x^2, x^3, x_1, x_2 \)
- Greek (Upper): Alpha, Beta, Gamma, etc.
- Greek (Lower): alpha, beta, gamma, etc.
- Arrows: \(\rightarrow, \leftrightarrow\)
- Other: \( (s), (l), (g), (aq) \)

**Options:**

- Submit Answer
- Retry Entire Group
- 9 more group attempts remaining

--- 

**Guide for Students:**

1. Identify the gaseous components in the reaction as solids and liquids are not included in the expression for \( K_p \).
2. Use the provided symbols to correctly format your answer.
3. Check if the reaction involves only solids, if so, the equilibrium constant, \( K_p \), would be determined by gases present.

In this reaction, since \( \text{O}_2 (g) \) is the only gaseous product, your expression for \( K_p \) will involve only this component.
