Chapter 24, Problem 24.22QP

Interpretation Introduction

Interpretation:

The standard enthalpy change in kilojoules per mole for the given reaction has to be calculated.

Concept introduction:

Enthalpy change of reaction: The enthalpy change of a reaction is roughly equivalent to the amount of energy lost or gained during the reaction.

$\begin{array}{l}{\text{ΔH}}_{\text{r}}{}^{\text{o}}\text{=}{\text{ΣnΔH}}^{\text{o}}\left(\text{products}\right)\text{-}{\text{ΣnΔH}}^{\text{o}}\left(\text{reactants}\right)\\ \text{where,}\\ \text{n}\text{is}\text{Stoichiometric}\text{coefficient}\end{array}$
