An example of a reversible reaction is:
  • a)
    Pb(NO3)2 (aq) + 2NaI (aq) = PbI2(s) + 2NaNO3(aq)
  • b)
    AgNO3(aq) + HCl(aq) = AgCl(s) + HNO3(aq)
  • c)
    2Na(s) + 2H2O(l) = 2NaOH(aq) + H2(g)
  • d)
    KNO3(aq) + NaCl(aq) = KCl(aq) + NaNO3(aq)
Correct answer is option 'D'. Can you explain this answer?

Weak acids and bases may undergo reversible reactions. For example, carbonic acid and water react this way:
H2CO3 (l) + H2O(l) ⇌ HCO−3 (aq) + H3O+(aq)
Another example of a reversible reaction is:
N2O4 ⇆ 2 NO2
Two chemical reactions occur simultaneously:
N2O4 → 2 NO2
2 NO2 → N2O4
Reversible reactions do not necessarily occur at the same rate in both directions, but they do lead to an equilibrium condition. If dynamic equilibrium occurs, the product of one reaction is forming at the same rate as it is used up for the reverse reaction. Equilibrium constants are calculated or provided to help determine how much reactant and product is formed.
The equilibrium of a reversible reaction depends on the initial concentrations of the reactants and products and the equilibrium constant, K.

Reversible Reaction Example

A reversible reaction is a chemical reaction in which the products can react to form the original reactants. An example of a reversible reaction is:

KNO3(aq) + NaCl(aq) ⇌ KCl(aq) + NaNO3(aq)

Explanation:

Reactants:
- Potassium Nitrate (KNO3) in aqueous form
- Sodium Chloride (NaCl) in aqueous form

Products:
- Potassium Chloride (KCl) in aqueous form
- Sodium Nitrate (NaNO3) in aqueous form

In this reaction, the forward reaction is the combination of KNO3 and NaCl to form KCl and NaNO3. The reverse reaction is the combination of KCl and NaNO3 to form KNO3 and NaCl.

This reaction is reversible because both the forward and reverse reactions occur at the same rate. The equilibrium constant (Kc) for this reaction is equal to 1, indicating that the concentrations of the reactants and products are equal at equilibrium.

Overall, this reaction demonstrates the concept of chemical equilibria and how reactions can be reversible.
