Understanding Equilibrium in Chemical Reactions

Very Easy General Chemistry Chemical Equilibrium

In a closed system, the chemical reaction between nitrogen gas (N₂) and hydrogen gas (H₂) produces ammonia (NH₃) as follows:

3 H₂(g) + N₂(g) <=> 2 NH₃(g)

At equilibrium, the concentrations of the reactants and products remain constant. Which of the following statements is true regarding the equilibrium state of this reaction?

The rate of formation of ammonia equals the rate of consumption of hydrogen.

The concentrations of nitrogen and hydrogen will continue to change.

More ammonia will be produced until all hydrogen is used up.

The reaction only occurs in one direction.
