Chapter 8.9, Problem 4CP

Interpretation Introduction

Interpretation:

Enthalpy of the given reaction is to be determined.

Concept introduction:

The standard enthalpy for a reaction is the amount of enthalpy, which is to occur at the standard conditions.

The enthalpy of a reaction is calculated as follows:

$\Delta H{°}_{rxn}={\displaystyle \sum \text{BE}}\left(\text{reactants}\right)-{\displaystyle \sum \text{BE}}\left(\text{products}\right)$

Here, BE (reactants)is the average value of bond enthalpy for the reactants and BE (products) is the average value of bond enthalpy for the products.
