Chapter 6, Problem 6.95P

(a)

Interpretation Introduction

Interpretation:

Rationalize following expression for solid/liquid saturation pressures

  $P_{sl}{}^{sat}=A+BT$

Concept Introduction:

For two phase systems, the Clapeyron equation is defined as:

  $\frac{d{P}^{sat}}{dT}=\frac{\Delta S^{sl}}{\Delta V^{sl}}$

Where $\Delta S^{sl}$ is the entropy change, $\Delta V^{sl}$ is volume change

(b)

Interpretation Introduction

Interpretation:

Rationalize following expression for solid/liquid saturation pressures

  $P_{sl}{}^{sat}=A+B\ln T$

Concept Introduction:

For two phase systems, the Clapeyron equation is defined as:

  $\frac{d{P}^{sat}}{dT}=\frac{\Delta H^{sl}}{T\Delta V^{sl}}$

Where $\Delta H^{sl}$ is the enthalpy change.
