Question

Diatomic nitrogen is added to the equilibrium system:
N₂(g) + H₂(g)

Diatomic nitrogen is added to the equilibrium system: N<sub>2</sub>(g) + H<sub>2</sub>(g) 2 NH<sub>3</sub>(g) + heat When a new equilibrium is established the concentration of H<sub>2</sub> will be ________ the amount at the original equilibrium,and the amount of NH<sub>3</sub> will be ________ the amount at the original equilibrium. A) greater than;greater than B) greater than;less than C) less than;greater than D) less than;less than E) Both changes will be impossible to determine.

2 NH₃(g) + heat
When a new equilibrium is established the concentration of H₂ will be ________ the amount at the original equilibrium,and the amount of NH₃ will be ________ the amount at the original equilibrium.

Quizplus · Accepted Answer

The addition of diatomic nitrogen will shift the equilibrium to the side with fewer moles of gas, which is the product side. This means that the concentration of H₂ will decrease and the concentration of NH₃ will increase. Therefore, the amount of H₂ will be less than the amount at the original equilibrium, and the amount of NH₃ will be greater than the amount at the original equilibrium. Choice C reflects this expectation.
