Chapter 4, Problem 4H.5E

(a)

Interpretation Introduction

Interpretation:

The substance with higher standard molar entropy has to be stated.

Concept Introduction:

The degree of randomness in a system is the measured according to its entropy.  Higher the entropy greater will be the disorder in the system.  The increasing order of molar entropy for the three phases of matter that is solid, liquid and gas is shown below.

    $\text{soild}<\text{liquid}<\text{gas}$
