For the equation, PCl3(g)+Cl2(g)↔PCl5(g), where Kc=0.50, for which set of values is the reaction still going in a forward direction?

M PCl3 Cl2 PCl5
(a) 0.010 0.078 3.9x10-4
(b) 3.3x10-3 0.036 5.8x10-3
(c) 0.021 0.043 6.5x10-3
(d) 0.052 0.017 4.0x10-4
  (a)
  (b)
  (c)
  (d)

For this same reaction (#22), if Q>K, which action below would tend to reverse the inequality if the reaction was also exothermic at that temperature?

  dropping the pressure
