Chapter 6, Problem 6.6P

Interpretation Introduction

(a)

Interpretation:

Vapor pressure of acetone at ${50}^{\circ }\text{C}$ should be estimated.

Concept introduction:

The Clausius-Clapeyron equation is defined as:

$\ln \left(p^{\ast }\right)=-\frac{\Delta H^{lv}}{R}\left(\frac{1}{T}\right)+C$   ...... (1)

Here, $p^{\ast }$ is the vapor pressure of the gas at temperature $T$, $\Delta H^{lv}$ is the latent heat of vaporization, and $R$ is the universal gas constant. $C$ is the constant.

Interpretation Introduction

(b)

Interpretation:

Vapor pressure of acetone at ${50}^{\circ }\text{C}$ is to be estimated using Antoine equation and its parameters from table B.4.

Concept introduction:

Antoine equation is used to determine the vapor pressure of any substance at the given temperature by the equation:

${\log }_{10}{p}^{\ast }\left(\text{mmHg}\right)=A-\frac{B}{T\left({}^{\circ }\text{C}\right)+C}$   ...... (4)

Here, $A,B\text{ and }C$ are the constants specific for a substance given in table B.4 of appendix B.

Interpretation Introduction

(c)

Interpretation:

Vapor pressure of acetone at ${50}^{\circ }\text{C}$ is to be estimated using AntoineP function in APEx.

Concept introduction:

AntoineP is the function in APEx used to calculate the vapor pressure of a pure substance at specific temperature.
