The reaction: 2SO₂(g) + O₂(g) = 2SO3(g) has an equilibrium constant, Kc = 4.4 Suppose a mixture contains 0.22 M SO₂, 0.16 M O2, and 0.25 M SO3. Calculate the value of Qc and predict whether the system is at equilibrium or not at equilibrium. If not at equilibrium, indicate the direction of net reaction. (A) Qc = 0.12; system is not at equilibrium; a net forward reaction occurs to form more SO3 (B) Qc = 7.1; system is not at equilibrium; a net forward reaction occurs to form more SO3 (C) Q = 8.1; system is not at equilibrium; a net back reaction occurs to form more SO₂ and 0₂ (D) Qc = 4.4; system is at equilibrium and there is no net reaction
