Chapter 13, Problem 13B.8AE

Interpretation Introduction

Interpretation:

The rotational partition function for ethene molecule has to be stated.

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 partition function that is represented as shown below.

  $q\equiv {\displaystyle \sum _i{g}_i{e}^{-\beta {\in }_i}}$

The rotational partition function for molecules is represented as shown below.

  $q^{\text{R}}=\frac{T}{{\theta }_{\text{r}}}$
