At a certain temperature,nitogen and hydrogen react to form ammonia:
N₂(g) + 3 H₂(g) ⇌ 2 NH₃(g)
When initial amounts of N₂,H₂,and NH₃ are mixed,the concentration of NH₃ increases.Which statement below is TRUE?

Quizplus · Accepted Answer

The reaction quotient (Q) can be defined as the ratio of the product of the molar concentrations of the reaction products to that of the reactants, each raised to the power of its stoichiometric coefficient. The equilibrium constant (Kc) for the given reaction can be written as follows: Kc = [NH₃]^2 / ([N₂] x [H₂]^3) If the concentration of NH₃ increases, it means that the reaction has not yet reached equilibrium. Therefore, Q < Kc in the forward direction of the reaction. In other words, there are more reactants than products, and the reaction will proceed in the forward direction to reach equilibrium. Hence, the correct choice is B, K_c > Q.
