The equilibrium constant Kp for the reaction I2(g) + Br2(g) ⇀↽ 2 IBr(g) + 11.7 kJ is 280 at 150◦C. Suppose that a quantity of IBr is placed in a closed reaction vessel and the system is allowed to come to equilibrium at 150◦C. When equilibrium is established, the pressure of IBr is 0.200 atm. What is the pressure of I2 at equilibrium?
