Chapter 4, Problem 4I.3E

(a)

Interpretation Introduction

Interpretation:

The standard enthalpy of vaporization of benzene at its boiling pointhas to be determined.

Concept Introduction:

The degree of randomness in a system is the predicted according to its respective entropy.  Higher the entropy greater will be the disorder in the system.  The mathematical expression for the calculation of entropy of the system is shown below.

$\Delta \text{S}°=\frac{\Delta \text{H}°}{\text{T}}$

(b)

Interpretation Introduction

Interpretation:

The standard entropy of vaporization of $\text{10}\text{g}{\text{C}}_{\text{6}}{\text{H}}_{\text{6}}$ has to be determined.

Concept Introduction:

Same as part (a).
