![### Chemical Equilibrium Question
**Select the single best answer.**
**At 425°C, \( K_p = 4.18 \times 10^{-9} \) for the reaction:**
\[ 2 \text{HBr}(g) \rightleftharpoons \text{H}_2(g) + \text{Br}_2(g) \]
**In one experiment, 0.20 atm of HBr(g), 0.085 atm of H₂(g), and 0.085 atm of Br₂(g) are introduced into a container. Is the reaction at equilibrium? If not, in which direction will it proceed?**
- Yes, the reaction is at equilibrium.
- No, the reaction is not at equilibrium and will proceed to the right.
- No, the reaction is not at equilibrium and will proceed to the left.
**Instructions:**
To determine whether the reaction is at equilibrium, you should compare the reaction quotient \( Q_p \) to the equilibrium constant \( K_p \).
The reaction quotient \( Q_p \) is calculated using the partial pressures of the gases:
\[ Q_p = \frac{P_{\text{H}_2} \cdot P_{\text{Br}_2}}{(P_{\text{HBr}})^2} \]
Substitute the given partial pressures into the expression:
\[ Q_p = \frac{(0.085 \, \text{atm}) \cdot (0.085 \, \text{atm})}{(0.20 \, \text{atm})^2} = \frac{0.007225}{0.04} = 0.180625 \]
Compare \( Q_p \) to \( K_p \):
- If \( Q_p < K_p \), the reaction will proceed to the right (toward the products).
- If \( Q_p > K_p \), the reaction will proceed to the left (toward the reactants).
- If \( Q_p = K_p \), the reaction is at equilibrium.
In this problem:
\[ Q_p = 0.180625 \]
\[ K_p = 4.18 \times 10^{-9} \]
Since \( Q_p \) is significantly greater than \( K_p \), the reaction will proceed to the left to reach equilibrium.
Therefore, the correct answer is:
- No, the reaction is not at equilibrium and will](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe0ae19d5-3750-41df-884f-8ca3aa31e002%2F5c5ce94c-b2b1-4c31-b1a4-86e423468d91%2Fxht34u9_processed.jpeg&w=3840&q=75)
