Questions & Step-by-Step Solutions

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.
