consider the reaction A+2B--->/<---C initial mixture: Qc= [C] / [A][B^2] = 387 K

Question

consider the reaction A+2B--->/<---C

initial mixture:

Qc= [C] / [A][B^2] = 387

Kc=2.72

Is the reaction at equilibrium? If not, in which direction will it proceed to reach equilibrium?

a The reaction is already at equilibrium.
b The reaction will proceed in reverse to form reactants.
c The reaction will proceed forward to form products.

Explanation / Answer

Since Qc > Kc, the reaction is currently on the product side so it is not in equilibrium. Thus to make it reach equilibrium, it must proceed in the reverse to form reactants. Thus, the answer is B.
