Given that the partial pressures are their respective mole fraction x total pressure, you can make an equation and solve for total pressure. (Tip: don't forget to cancel as much as you can)
Kp = (pSO2)2 x(pO2) / (pSO3)2 Given that the partial pressures are their respective mole fraction x total pressure, you can make an equation and solve for total pressure. (Tip: don't forget to cancel as much as you can)
