Chapter 11, Problem 11.36QE

Interpretation Introduction

Interpretation:

The enthalpy of vaporization of dichlorobenzene has to be calculated.

Concept Introduction:

Enthalpy of fusion:  It is the enthalpy change that occurs when one of solid is converted to liquid at a constant temperature.

Enthalpy of vaporization:  It is the enthalpy change that accompanies the conversion of one mole of a substance from the liquid state to the gaseous state at constant temperature.

Enthalpy of sublimation:  It is the enthalpy change for the conversion of one mole of solid to the gaseous state.  The enthalpy of sublimation is the sum of enthalpy of fusion and the enthalpy of vaporization.
