A container at 12.0 °C initially contains AB (g) in equilibrium with AB (l):


AB (l) ⇔ AB (g)


A catalyst (of negligible volume) is added to the container such that AB (g) quickly decomposes and reaches equilibrium at 12.0 °C according to the reaction:


AB(g) ⇔ A(g) + B(g)    Kp = 2.20 at 12.0 °C


If the initial total pressure of the container (with AB only) is 1.46 bar, what is the total pressure (in bar) of the container (still containing liquid AB) at equilibrium? Assume A and B do not condense and are insoluble in liquid AB.
