At a certain temperature,hydrogen and iodine react to form hydrogen iodide: H₂(g) + I₂(g) ⇌ 2 HI(g) .
When initial amounts of H₂,I₂,and HI are mixed,the concentration of HI increases.Which statement below is true?

If the concentration of HCl increases, the reaction will shift towards the reactants to reach equilibrium. This means that the product concentration will decrease and the reactant concentration will increase until the reaction quotient, Q, equals the equilibrium constant, K. Since the concentration of the product (HCl) is increasing and the reaction is proceeding towards the product side, the reaction quotient Q is less than the equilibrium constant K, and therefore, K_c > Q.
