The Equilibrium Constant Is Equal to 5

question 41

Multiple Choice

The equilibrium constant is equal to 5.00 L mol^-1 at 1300 K for the reaction: 2SO₂(g) + O₂(g) ⇌ 2SO₃(g)
If initial concentrations are [SO₂] = 6.00 mol L^-1, [O₂] = 0.45 mol L^-1, and [SO₃] = 9.00 mol L^-1, the system is ________.

• A) at equilibrium
• B) not at equilibrium and will remain in an unequilibrated state
• C) not at equilibrium and will shift to the left to achieve an equilibrium state
• D) not at equilibrium and will shift to the right to achieve an equilibrium state
