Questions & Step-by-Step Solutions

For the equilibrium reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), what happens if SO3 is removed?
  • Step 1: Identify the reaction: 2SO2(g) + O2(g) ⇌ 2SO3(g).
  • Step 2: Understand that this reaction is in equilibrium, meaning the forward and reverse reactions are happening at the same rate.
  • Step 3: Recognize that removing SO3 decreases its concentration in the system.
  • Step 4: Know that when the concentration of a product (SO3) decreases, the system will try to restore balance.
  • Step 5: The system shifts to the right, which means it will produce more SO3 from SO2 and O2.
  • Step 6: This shift continues until the concentration of SO3 is restored to a new equilibrium.
  • 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 right or left) based on changes in concentration of reactants or products.
