Question: For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g), what happens if H2 is removed from the system?

Options:

Correct Answer: Equilibrium shifts to the left

Solution:

Removing H2 decreases its concentration, causing the equilibrium to shift to the left to produce more reactants and restore balance.

For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g), what happens if H2 is removed from the system?

Step 1: Identify the reaction: N2(g) + 3H2(g) ⇌ 2NH3(g).
Step 2: Understand that H2 is a reactant in this reaction.
Step 3: Recognize that removing H2 decreases its concentration in the system.
Step 4: Know that when the concentration of a reactant decreases, the system tries to restore balance.
Step 5: The system shifts the equilibrium to the left, which means it will produce more reactants (N2 and H2).
Step 6: This shift helps to increase the concentration of H2 back towards its original level.

Le Chatelier's Principle – When a system at equilibrium is disturbed, it will shift in a direction that counteracts the disturbance.
Equilibrium Shift – The direction of the shift in equilibrium (to the left or right) based on changes in concentration of reactants or products.
