Chapter 17, Problem 17.49E

Interpretation Introduction

Interpretation:

The reason as to why the calculated value for the absolute entropy of $\text{Kr}$ at $120\text{K}$ might not be very close to the experimental value, even though the boiling point of $\text{Kr}$ is $119.8\text{K}$ is to be stated.

Concept introduction:

Statistical thermodynamics is used to describe all possible configurations in a system at given physical quantities such as pressure, temperature and number of particles in the system. An important quantity in thermodynamics is the partition function that is represented as,

$q={\left(\frac{2\pi mkT}{h^2}\right)}^{3/2}\cdot V$

It is used to calculate the state functions like energy, pressure, wavelength etc. of the thermodynamic system. The expressions obtained for state functions using partition functions help to determine the statistical aspect of thermodynamic system.
