reversible reactions and equilibria

• What is a sealed container?

  when no substance are added to the reaction and no substances escape from it
• What is dynamic equilibrium?

  when the rate of the forward reaction is equal to the rate of the reverse reaction
• describe dynamic equilibriam.

  - the rate of the forward reaction is equal to the rate of the reverse reaction

  - it occurs only in a sealed container

  - the total concentration of reactants and products remains constant.
