If Q (reaction quotient) > K_c at some instant, the reaction will:

1. Q < K → forward direction favoured (too few products). 2. Q = K → already at equilibrium. 3. Q > K → reverse direction favoured (too many products). 4. So the reaction goes BACK, making more reactants until Q = K. _Source: NCERT Class 11 Chem Ch 7 §7.5 Reaction Quotient_
