Question

The equilibrium constant Kp for the oxidation of sulfur dioxide into sulfur trioxide is 5.6×10-4 at 3500°C. If the equilibrium partial pressures of SO2 and SO3 are 0.64 atm and 0.58 atm, respectively, what is the partial pressure of O2 in the system?

  2SO2(g) + O2(g) —› 2SO3 (g)

Answer 1

Solution:

Balanced chemical equation:

2SO₂(g) + O₂(g) → 2SO₃(g)

The equilibrium expression for the reaction:

Therefore,

Answer: The partial pressure of O₂ is 1466.59 atm.
