The equilibrium constant at 357 K for the reaction Br2(g) + I2(g) ? 2IBr(g) has a value of 0.2029. Bromine at an initial pressure of 0.0531 atm is mixed with iodine at an initial pressure of 0.0696 atm and held at 357 K until equilibrium is reached. What is the partial pressure of Br2 at equilibrium? What is the partial pressure of I2 at equilibrium? What is the partial pressure of IBr at equilibrium?
