Chapter 13, Problem 13E.10P

Interpretation Introduction

Interpretation:

The standard molar entropy of ${\text{N}}_{\text{2}}\left(\text{g}\right)$ at $\text{298}\text{K}$ from its rotational constant has to be calculated. The suggestion about this solid at $T=0$ is to be stated.

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 standard molar entropy.
