Concentration and Reversible Reactions

• What happens at equilibrium in a reversible reaction?

  The forward and reverse reactions occur at the same rate
• What is the term used when a system responds to counteract a change at equilibrium?

  Le Chatelier's principle
• What happens if the concentration of NO2 is increased in the reaction forming N2O4?

  More N2O4 will be formed until equilibrium
• What occurs when the concentration of N2O4 is decreased?

  More NO2 will react to form N2O4
• What happens if the concentration of N2O4 is increased again?

  More NO2 will be formed until equilibrium
• What is meant by a sealed container in reversible reactions?

  • No reactants or products can escape
  • Ensures constant conditions for the reaction
• How does the system respond to changes in concentration?

  • It adjusts the rates of forward and reverse reactions
  • Aims to restore equilibrium after a disturbance
