Chapter 17, Problem 17.126CP

Interpretation Introduction

Interpretation:

Boiling point of ethanol should be calculated using Gibb’s free energy equation

Concept Introduction:

$\text{ΔG}$ is the Gibbs energy which is calculated using Gibbs-Helmholtz equation,

$\text{ΔG=ΔH}-\text{TΔS}$

$\text{ΔH}$ is the change in enthalpy of the system
T is the temperature of the system
$\text{ΔS}$ is the change in entropy of the system

To determine:

Calculate the normal boiling point of ethanol given that its enthalpy of vaporization is 38.6 KJ/mole and its entropy of vaporization is 110 J/Kmole
