Concept introduction: The Gibbs free energy or the free energy change is a thermodynamic quantity represented by Δ r G ∘ . It is related to entropy and entropy by the following expression, Δ r G ∘ = Δ r H ∘ − T Δ r S ∘ Here, Δ r H ∘ is the change in enthalpy and Δ r S ∘ is the change in entropy. The value of Δ r G ∘ is zero at the boiling point of the liquid. Thus the entropy change can be written as, Δ r S ∘ = Δ r H ∘ T Thus, the temperature at which vaporization takes place can be calculated if Δ r H ∘ and Δ r S ∘ values are known.Start your trial now!

Interpretation Introduction

**Interpretation:**

The normal boiling point of ethanol should be estimated using thermodynamic data which then has to be identified that how well it agreed with the actual value.

**Concept introduction:**

The Gibbs free energy or the free energy change is a thermodynamic quantity represented by

Here,

The value of

Thus, the temperature at which vaporization takes place can be calculated if
