Entropy is a measure of degree of randomness. Entropy is directly proportional to temperature. Every system tries to acquire maximum state of randomness or disorder. Entropy is a measure of unavailable energy. Unavailable energy = Entropy × Temperature The ratio of Entropy of Vaporization and boiling point of a substance remains almost constant. Answer the given below questions (i) to (iv).

  • a)
    Adsorption
  • b)
    Dissolution of NH4Cl in water
  • c)
    H2 → 2H
  • d)
    2NaHCO3 (s) → Na2CO3 + CO2 + H2O

Adsorption:
Adsorption is a process where molecules or particles adhere to the surface of a solid or liquid. In this process, entropy is usually negative because the molecules are becoming more ordered as they are attaching to the surface.

Dissolution of NH4Cl in water:
When NH4Cl dissolves in water, it undergoes a process where entropy increases. This is because the molecules of NH4Cl are becoming more dispersed in the solvent, leading to an increase in randomness.

H2 → 2H:
In the reaction H2 → 2H, the number of molecules increases from 1 to 2, leading to an increase in randomness and hence a positive entropy change.

2NaHCO3 (s) → Na2CO3 + CO2 + H2O:
In this reaction, solid NaHCO3 decomposes into three different products. The formation of multiple products increases the randomness in the system, resulting in a positive entropy change.

Therefore, the process of adsorption typically has a negative entropy change, as the molecules become more ordered on the surface.
