    Under different conditions, 40% of the moles present at equilibrium is N2O4.

    If the total pressure of the system is 2.0 atm. The numerical value of the equilibrium constant Kp is ????

    partial pressure = mole fraction x total pressure

    partial pressure = mole fraction x total pressure
    Kp= 0.40*2.0?
    Is 2.0 atm = just 2?

    You have to work out the partial pressure of each component

    Then apply the equilibrium law ...
