Question
Chapter 6, Problem 6.34E
Interpretation Introduction
Interpretation:
The normal boiling point of benzene is to be estimated.
Concept introduction:
The Clausius-Clapeyron equation is obtained from the rearrangement and integration of Clapeyron equation. The Clausius-Clapeyron equation is generally used for gas-phase equilibria, to predict the equilibrium temperatures and pressures and also for the determination of enthalpy for phase transition.
