Chapter 3, Problem 3B.3P

Interpretation Introduction

Interpretation: The value of change in molar entropy if ${\text{CHCl}}_{\text{3}}$ is heated from $\text{273}\text{K}$ to $\text{300}\text{K}$ has to be calculated.

Concept introduction: The randomness present in the system is called its entropy.  It is an extensive property.  At equilibrium, the entropy of the system is zero.  It is denoted by $S$.  The entropy that is measured under the standard conditions of temperature is known as standard entropy.  The standard entropy is denoted by $\Delta S$.  The entropy for one mole of the substance under standard conditions is called molar entropy.
