Chapter 18, Problem 18.16E
Interpretation Introduction

(a)

Interpretation:

The value of qelect for He2 at 4.2K is to be calculated.

Concept introduction:

The point at which the bond between the two atoms become nonexistent thus the molecule exists as two separated atoms are 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 points.

Interpretation Introduction

(b)

Interpretation:

Whether it is expected that He2 exist at room temperature (300K) or not is to be stated. The explanation corresponding to the answer is to be stated.
