Chapter 16, Problem 81AE

Interpretation Introduction

Interpretation: The value of $\Delta S°$ is given for the formation reactions of $\text{Fe}{\left(\text{CO}\right)}_{\text{5}}\left(g\right)$ and $\text{Fe}{\left(\text{CO}\right)}_{\text{5}}\left(l\right)$. The value of $S°$ for $\text{Fe}{\left(\text{CO}\right)}_{\text{5}}\left(g\right)$ by using Appendix $4$, is to be calculated.

Concept introduction: The expression for standard entropy change, $\Delta S°$, is,

$\Delta S°=\sum n_{\text{p}}\Delta S{°}_{\left(\text{product}\right)}-\sum n_{\text{f}}\Delta S{°}_{\left(\text{reactant}\right)}$
