Chapter 8, Problem 8.20NP
Interpretation Introduction

Interpretation: The normal boiling point and the normal standard point are to be calculated for liquid benzene. Whether the obtained result agrees with the value in the mentioned table or not should be explained.

Concept introduction: Normal boiling point is the point when the pressure becomes equal to 1 atm . The standard boiling point is the point when the pressure becomes equal to 1 bar . According to the Clausius Clapeyron equation, the rate at which the natural logarithm of the vapor pressure of a particular liquid changes with temperature is calculated by using the enthalpy of vaporization of the liquid, universal gas constant, and temperature of the system.
