3. Determine if the following system is at equilibrium. If not, in which direction will the system need to shift to reach equilibrium? SO2Cl2(g) ⇌ SO2(g)+Cl2(g) [SO2Cl2] = 0.12 M, [Cl2] = 0.16 M and [SO2] = 0.050 M. Kc for the reaction is 0.078.

Answer:

The system need to shift to the right

Explanation:

For the reaction:

SO2Cl2(g) ⇌ SO2(g)+Cl2(g)

Reaction quotient, Q, is:

Q = [SO2] [Cl2] / [SO2Cl2]

If Q = Kc, the system is in equilibrium, if Q > Kc, the system need to shift to the left, if Q < Kc,  the system need to shift to the right.

Replacing:

Q = 0.050 M×0.16 M / 0.12 M

Q = 0.067

As Kc = 0.078, Q < Kc, the system need to shift to the right.

I hope it helps!
