If Q (reaction quotient) > K_c at some instant, the reaction will:
AProceed forward only
BBe at equilibrium now
CReverse to make reactants
DStop the reaction entirely
Answer & Solution
Correct answer: C. Reverse to make reactants
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.
