2 50₂ (9) + O₂(g) 2 SO, (g) K, = 2 × 10³ At a certain temperature, SO, (g) and O₂(g) react to produce 80₁ (9) according to the chemical equation shown above. An evacuated rigid vessel is originally filled with SO₂ (g) and O₂(g), each with a partial pressure of 1 atm. Which of the following is closest to the partial pressure of O₂(g) after the system has reached equilibrium, and why? 0 atm because K, is very large, nearly all the SO₂ (g) and O₂(g) are consumed before the system reaches equilibrium 0.5 atm, because K, is very large, nearly all the SO₂ (g) is consumed before the system reaches equilibrium, but an excess amount of O₂(g) remains at equilibrium 1 atm; because K, is very large, the system is already near equilibrium, and there will be very little change to the partial pressure of O(g) 1.5 atm because K, is very large, the decomposition of any SO, (a) that forms increases the amount of O,(g) at equilibrium 2 50₂ (9) + O₂(g) 2 SO, (g) K, = 2 × 10³ At a certain temperature, SO, (g) and O₂(g) react to produce 80₁ (9) according to the chemical equation shown above.
