Question

In this reaction, N2(g) + 3H2(g) -> 2NH3(g), if Q = Keq, which statement is true?

A) The reaction will move forward.
B) The reaction will move in reverse.
C) The concentration of the product should increase.
D) The reaction is in equilibrium.

Answer 1

The reaction quotient Q being equal to the equilibrium constant Keq indicates that the reaction is at equilibrium, with no net change in the concentrations of reactants and products.

Step-by-step explanation:

When the reaction quotient Q is equal to the equilibrium constant Keq for the reaction N₂(g) + 3H₂(g) → 2NH₃(g), this means that the system is at equilibrium. The concentrations of the reactants and products will remain constant unless the system is disturbed. If Q = Keq, there will be no net change in the direction of the reaction; it is balanced between the forward and reverse reactions. Therefore, the correct statement is D) The reaction is in equilibrium.
