Chapter 13, Problem 13E.9P

Interpretation Introduction

Interpretation:

The rotational contribution to the molar entropy on a different range of temperature has to be calculated. The graph for the rotational contribution as a function of temperature has to be plotted.

Concept introduction:

Statistical thermodynamics is used to describe all the possible configurations in a system at given physical quantities such as pressure, temperature, and a number of particles in the system.  The important quantity in the thermodynamic is the partition function.  The rotational partition function is calculated by the formula shown below.

  $q^{\text{R}}={\displaystyle \sum _J\left(2J+1\right)}{\text{e}}^{-\beta hc\tilde{B}J\left(J+1\right)}$
