Consider the following reaction and its equilibrium constant: SO₂(g) + NO₂(g) ⇌ SO₃(g) + NO(g) K_c = 0.33
A reaction mixture contains 0.41 M SO₂,0.14 M NO_2, 0.12 M SO₃ and 0.14 M NO.Which of the following statements is TRUE concerning this system?

Question

Quizplus · Accepted Answer

The reaction quotient Qc can be calculated as follows: Qc = [SO₃][NO] / [SO₂][NO_2,] Qc = (0.12)(0.14) / (0.41)(0.14) = 0.033 Since the equilibrium constant Kc is greater than Qc, the system is not at equilibrium and the reaction will shift in the direction of products to reach equilibrium. Therefore, the correct answer is choice C.
