First, we need to write the expression for the equilibrium constant in terms of the given concentrations: K_c = ([SO₃]_eq)^2/[O₂]_eq Substituting the values given: 1.7 × 10⁸ = (0.0034 M)^2/(0.0018 M) Solving for [SO₂]_eq: [SO₂]_eq = (K_c x [O₂]_eq)/([SO₃]_eq)^2 = (1.7 × 10⁸ x 0.0018 M)/(0.0034 M)^2 = 6.1 × 10^-6 M Therefore, the equilibrium concentration of SO₂(g) is 6.1 × 10^-6 M, which is option C.
