Expert Solution
Step 1

The direction in which the reaction proceeds to reach equilibrium can be predicted by finding reaction quotient (Qc) value and comparing with equilibrium constant (Kc) value

If Qc<Kc , reaction will proceed in forward direction

If Qc>Kc , reaction will proceed in reverse direction

If Qc=Kc , reaction is at equilibrium
