The equation which represents the chemical equilibrium is  2 NO₂ ⇄ N₂0₄

Explanation:

  • The equation which represents the chemical equilibrium is

           2 NO₂ ⇄ N₂0₄.

  • A chemical reaction is in equilibrium at the combinations of reactants and products are even  and their ratio does not change
  • In other words, the equilibrium can be defined as the system is in equilibrium when the forward and backwards reactions happen at regular rates.
  • The idea of chemical equilibrium was formed after Berthollet found that some chemical reactions are reversible.
