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] = 0.10 M; [SO₃] = 10. M; [O₂] = 0.10 M. Which of the following is true based on the above

Question

Quizplus · Accepted Answer

Q_c = [SO₃]² / [SO₂]²[O₂] = (10. M)² / (0.10 M)²(0.10 M) = 10⁴ < K_c = 4.3 * 10⁶, so the reaction proceeds from left to right to reach equilibrium.

At 700 K, the Reaction 2SO2(g) + O2(g) ⇌ 2SO3(g)

At 700 K, the Reaction 2SO₂(g) + O₂(g) ⇌ 2SO₃(g)
