At 700 K, the reaction 2SO₂(g) + O₂(g) ⇌ 2SO₃(g) has the equilibrium constant K_c = 4.3 * 10⁶, and the following concentrations are present: [SO₂] = 0.010 M; [SO₃] = 10. M; [O₂] = 0.010 M. Which of the following is true based on the above

Question

Quizplus · Accepted Answer

The reaction quotient, $Q_c$, is calculated using the concentrations of the reactants and products. For this reaction, $Q_c = \frac{[SO_3]^2}{[SO_2]^2[O_2]}$. Substituting the given concentrations, $Q_c = \frac{(10)^2}{(0.010)^2(0.010)} = \frac{100}{0.0001} = 1 \times 10^6$. Since $Q_c = 1 \times 10^6$ is greater than $K_c = 4.3 \times 10^6$, the reaction will proceed from right to left to reach equilibrium.
