Chapter 4, Problem 4B.2ST

Interpretation Introduction

Interpretation:

Normal boiling point of benzene has to be estimated with the given information.

Concept introduction:

Clausius-Clapyron equation,

$\text{ln}\frac{{\text{P}}_{\text{2}}}{{\text{P}}_{\text{1}}}\text{=}\frac{{\text{ΔH}}_{\text{vap}}}{\text{R}}\left(\frac{\text{1}}{{\text{T}}_{\text{2}}}\text{-}\frac{\text{1}}{{\text{T}}_{\text{1}}}\right)\boxed{\begin{array}{l}\text{where,}\\ {\text{ΔH}}_{\text{vap}}:\text{Enthalpy}\text{of}\text{vaporization}\\ \text{R}:\text{Gas}\text{constant}\\ \text{P}:\text{Pressure}\\ \text{T}:\text{Temperature}\end{array}}$

A general expression for calculating vapor pressure:

  $\begin{array}{l}\text{ln}\text{p}\text{=}\text{A}\text{-}\frac{\text{B}}{\text{T}}\\ \\ \text{A}\text{and}\text{B}\text{are}\text{constants}\\ \\ \text{T}\text{-Temperature}\text{in}\text{K}\end{array}$
