Chapter 18, Problem 18.23E
Interpretation Introduction

Interpretation:

The vibrational partition function for NO2(g) at 250K, 500K, and 1000K are to be calculated. Whether the changes in qvib show the expected differences or not is to be stated.

Concept introduction:

A molecule is made up of atoms that are bonded together by covalent bonds. These bonds undergo a to and fro movement to vibrate. This vibration of the molecule contributes to the overall partition function of the system. The vibrational partition function of the polyatomic molecule is represented as,

qvib=j=13N611eθv,j/T

Where,

T represents the temperature (K).

θv,j represents the jth vibrational temperature.

N represents the number of atoms present in the molecule.
