Chapter 5, Problem 5.129AP

Interpretation Introduction

Interpretation: The standard molar enthalpy of for the complete combustion of liquid ethanol with the use of Appendix $4$ is to be calculated.

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

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

To determine: The standard molar enthalpy of for the complete combustion of liquid ethanol.
