Chapter 9, Problem 9.42P
Interpretation Introduction

Interpretation:

A solution plan to calculate the total enthalpy change of the following reaction is to be written

H2(g)+O2(g)H2O2(g)

Concept introduction:

The heat of the reaction (ΔHrxn°) is defined as the heat released or absorbed during a chemical reaction as a result of the difference in the bond energies(BE) of reactant and product in the reaction. ΔHrxn° is negative for exothermic reaction and ΔHrxn° is positive for an endothermic reaction.

The formula to calculate ΔHrxn° of reaction is as follows:

ΔHrxn°=ΔHreactant bond broken°+ΔHproduct bond formed°

Or,

ΔHrxn°=BEreactant bond brokenBEproduct bond formed
