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)
Balanced chemical equation:
2SO2(g) + O2(g) → 2SO3(g)
The equilibrium expression for the reaction:
Answer: The partial pressure of O2 is 1466.59 atm.
