Chapter 5, Problem 5.14NP

Interpretation Introduction

Interpretation:

The value of $\Delta S^0$ needs to be calculated for the reaction ${\text{3H}}_{\text{2}}\left(\text{g}\right){\text{ + N}}_{\text{2}}\left(\text{g}\right)\to {\text{2NH}}_{\text{3}}\left(\text{g}\right)$ at 725 K.

Concept Introduction :

The entropy of reaction could be found using the following equation.

  $\Delta S^0{}_R={\displaystyle \sum _i{V}_i{S}_i{}^0}$

Here the subscript i denotes each species and V_i is the coefficient of each species in the balanced reaction equation.
