Chapter 4, Problem 4D.13E

Interpretation Introduction

Interpretation:

The reaction enthalpy for the production of metallic bariumhas to be determined.

Concept Introduction:

Hess’s law is defined as the law which states that the enthalpy of a reaction does not depend on the path followed by reaction.  It depends only on the standard enthalpy of formations for estimating the enthalpy of a reaction.  The standard enthalpy of reaction that is ${\Delta }_{\text{r}}H°$ is the enthalpy of the reaction which involves pure reactants and pure products in their standard states at a particular temperature.
