Chapter 11, Problem 58E

Interpretation Introduction

(a)

Interpretation:

Among ${\text{H}}_{\text{2}}\text{O}$ and ${\text{H}}_{\text{2}}\text{Se}$, the compound having higher heat of vaporization is to be stated.

Concept introduction:

The heat of vaporization is the amount of heat required to convert the liquid state to the gaseous state. The heat of vaporization of a compound is directly proportional to its intermolecular forces of attractions and the molar mass of the compound.

Interpretation Introduction

(b)
