Options:
  • A If \( Q_{C}>K_{C} \), the reverse reaction isfavoured
  • B If \( Q_{C} < K_{C} \), the forward reaction is favoured
  • C If \( Q_{C}=K_{C} \), forward reaction is favoured
  • D If \( Q_{C}>K_{C} \), forward reaction is favoured

The correct answer is: If \( Q_{C}>K_{C} \), forward reaction is favoured
$Q_{C}>K_{C}$, reverse reaction is favored. The product concentration is more than
the equilibrium concentration. The reactant concentration is less than the equilibrium concentration.
If $Q_{C} < K_{C}$ forward reaction is favored.
If $Q_{C}=K_{C}$ the reaction is at equilibrium that is dynamic. Both forward and
reverse reactions continue to occur.
Hence, the correct options are $C$ and $D$
