Chapter 18, Problem 18.13E
Interpretation Introduction

Interpretation:

The value of in qelect at 298K for H2 if De is used as the dissociation energy instead of D0 is to be predicted.

Concept introduction:

The point at which the bond between the two atoms become nonexistent and the molecule exits as two separated atoms is known as dissociation limit. The relation between D0 and De is given by the formula,

D0=De12hv

Where,

D0 represents dissociation energy.

h is the Plank’s constant.

v is vibrational frequency.

De is the minimum potential energy of ground electronic state with respect to the zero point.

The vibrational energy levels for XO molecule can be described by the following formula: E(n) in Joule = 1.88x10-20(n+1/2) – 2.68x10-22(n+1/2)² where n is the vibrational quantum number. What would be the equilibrium dissociation energy (De) of the XO molecule in a kJ mol-1?
