Question

The equilibrium constant, K_p, for the reaction H₂(g) + I₂(g)

The equilibrium constant, K<sub>p </sub>, for the reaction H<sub>2</sub>(g) + I<sub>2</sub>(g) 2HI(g) Is 55.2 at 425°C. A rigid cylinder at that temperature contains 0.127 atm of hydrogen, 0.134 atm of iodine, and 1.055 atm of hydrogen iodide. Is the system at equilibrium? A) Yes. B) No, the forward reaction must proceed to establish equilibrium. C) No, the reverse reaction must proceed to establish equilibrium. D) Need to know the volume of the container before deciding. E) Need to know the starting concentrations of all substances before deciding.
