The formula equation shows a reversible reaction is:

NH₄Cl(s) ⇄ NH₃(g) + HCl(g)

Classification of reactions according to their reversibility

  • Reversible reactions: They occur in both senses, as denoted by a double arrow.
  • Irreversible reactions: They occur in one sense, as denoted by a single arrow.

Let's consider which formula equation shows a reversible reaction.

  • 2 Na + F₂ ⇒ 2 NaF

The single arrow indicates that this is an irreversible reaction.

  • CaCO₃ ⇒ CaO + CO₂

The single arrow indicates that this is an irreversible reaction.

  • NH₄Cl(s) ⇄ NH₃(g) + HCl(g)

The double arrow indicates that this is a reversible reaction.

  • 2 H₂O₂(aq) ⇒ 2 H₂O(l) + O₂(g)

The single arrow indicates that this is an irreversible reaction.

The formula equation shows a reversible reaction is:

NH₄Cl(s) ⇄ NH₃(g) + HCl(g)
