Consider the following reaction and its equilibrium constant: SO₂(g) + NO₂(g) ⇌ SO₃(g) + NO(g) K_c = 0.33
A reaction mixture contains 1.0 mol L^-1 SO₂, 2.0 mol L^-1 NO₂, 0.66 mol L^-1 SO₃, and 1.0 mol L^-1 NO. Which of the following statements is TRUE concerning this system?

Question

Quizplus · Accepted Answer

The reaction mixture has the same amount of moles on both sides of the equation as the stoichiometric coefficients are 1:1, 1:1, 1:1, and 1:1. Therefore, the reaction will be at equilibrium, and there will be no shift in the direction of either reactants or products. The equilibrium constant will remain the same as well. The reaction quotient Qc can be calculated, and it will be equal to the equilibrium constant Kc, indicating that the system is already at equilibrium.
