Consider the following system at equilibrium where AH° =-87.9 kJ, and K. = 83.3 , at 500 K: %3D PCI3 (g) + Cl2 (g) =PCI5 (g) If the TEMPERATURE on the equilibrium system is suddenly increased : The value of K, A. Increases B. Decreases C. Remains the same The value of Q. A. Is greater than K. B. Is equal to Kc C. Is less than K. The reaction must: A. Run in the forward direction to restablish equilibrium. B. Run in the reverse direction to restablish equilibrium. C. Remain the same. Already at equilibrium. The concentration of Cl, will: A. Increase. B. Decrease. C. Remain the same.
