![For the reaction:
\[ 2 \text{SO}_2(g) + \text{O}_2(g) \rightleftharpoons 2 \text{SO}_3(g) \]
the equilibrium constant is \( K_c = 15 \, \text{M}^{-1} \) at 850 K.

1. \([ \text{SO}_2 ] = 0.20 \, \text{M}\)
\([ \text{O}_2 ] = 0.60 \, \text{M}\)
\([ \text{SO}_3 ] = 0.60 \, \text{M}\)
2. \([ \text{SO}_2 ] = 0.72 \, \text{M}\)
\([ \text{O}_2 ] = 0.69 \, \text{M}\)
\([ \text{SO}_3 ] = 0.63 \, \text{M}\)
3. \([ \text{SO}_2 ] = 0.12 \, \text{M}\)
\([ \text{O}_2 ] = 0.12 \, \text{M}\)
\([ \text{SO}_3 ] = 0.56 \, \text{M}\)
Determine the reaction quotient \( Q_c \) for each set and compare it with \( K_c \) to find the direction the reaction will proceed to reach equilibrium.
Steps:
1. Calculate \( Q_c = \frac{[\text{SO}_3]^2}{[\text{SO}_2]^2 [\text{O}_2]} \) for each set.
2. Compare \( Q_c \) with \( K_c \):
- If \( Q_c < K_c \): Reaction shifts right.
- If \( Q_c > K_c \](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F28c94148-80c1-43f5-a0b3-f515c4a2b9a8%2Ffa3e1fe5-5780-4fdf-8c46-3952e8612daf%2Fc1ihrgg_processed.png&w=3840&q=75)

Expert Solution
Step 1
The given reaction is:
1) [SO2] = 0.20 M
[O2] =0.60 M
[SO3]=0.60 M
Calculation of Qc:
Since Qc=Kc, thus there will be no change.
