Question

Consider the following reaction at equilibrium: 2NH₃ (g)

Consider the following reaction at equilibrium: 2NH<sub>3</sub> (g) N<sub>2</sub> (g) + 3H<sub>2</sub> (g) ΔH° = +92.4 kJ Le Châtelier's principle predicts that adding N<sub>2</sub> (g) to the system at equilibrium will result in __________. A) a decrease in the concentration of NH<sub>3</sub> (g) B) a decrease in the concentration of H<sub>2</sub> (g) C) an increase in the value of the equilibrium constant D) a lower partial pressure of N<sub>2</sub> E) removal of all of the H<sub>2 </sub>(g)

N₂ (g) + 3H₂ (g) ΔH° = +92.4 kJ
Le Châtelier's principle predicts that adding N₂ (g) to the system at equilibrium will result in __________.

Quizplus · Accepted Answer

According to Le Châtelier's principle, adding N₂ (g) to the system will shift the equilibrium to the right to counteract the increase in concentration of N₂ (g). This means that more NH₃ (g) and H₂ (g) will react to form more N₂ (g). Therefore, the concentration of H₂ (g) will decrease. None of the other choices are consistent with Le Châtelier's principle.
