Chapter 5.8, Problem 15PE

Interpretation Introduction

Interpretation: The enthalpy change $\left(\Delta H_{\text{rxn}}^{\text{ο}}\right)$ for the given water $-$ gas shift reaction is to be calculated.

Concept introduction: The enthalpy change for a reaction $\left(\Delta H_{\text{rxn}}^{\text{ο}}\right)$ is calculated by the formula,

$\Delta H_{\text{rxn}}^{\text{ο}}={\displaystyle \sum n\times \Delta H_{\text{f}}^{\text{ο}}\left(\text{Products}\right)}-{\displaystyle \sum m\times \Delta H_{\text{f}}^{\text{ο}}\left(\text{Reactants}\right)}$

To determine: The enthalpy change $\left(\Delta H_{\text{rxn}}^{\text{ο}}\right)$ for the given water $-$ gas shift reaction.
