Cl2(g) + F2(g) <===> 2 ClF(g) Kc = 19.9 For the reaction forming ClF the initial concentrations are as follows: [Cl2] = 0.5 M ; [F2] = 0.2 M ; [ClF] = 7.3 M Is the reaction at equilibrium? If not, in which direction with the reaction shift to reach equilibrium?

a) Yes, the reaction is at equilibrium. b) Reaction needs to shift towards products to reach equilibrium.

c) Reaction needs to shift toward reactants to react equilibrium.

d) Insufficient information provided to make a decision.
