![**Chemical Equilibrium Problem**
*Reaction:*
\[ 2 \text{H}_2\text{O(g)} \rightleftharpoons 2 \text{H}_2\text{(g)} + \text{O}_2\text{(g)} \]
\[ K_p = 7.20 \times 10^{-81} \text{ at 250 °C} \]
**Problem Statement:**
A sealed, rigid vessel contains only H₂(g) and O₂(g) at initial pressures of 0.50 atm and 0.40 atm, respectively. When equilibrium is reached at 250 °C, what is the pressure of O₂?
*Instructions:*
To solve this, apply the concept of chemical equilibrium using the equilibrium constant \( K_p \). Determine the changes in pressures required to reach equilibrium and calculate the equilibrium pressure of O₂ given the initial conditions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6d7773ea-2418-45b6-94fc-b17f139a153f%2F787cd92b-8a67-4bbd-b713-cd64b463fff9%2Frzkbtxj_processed.jpeg&w=3840&q=75)
