Chapter 9, Problem 9.105SP

Interpretation Introduction

Interpretation:

The value of ΔH⁰ f (in kilojoules per mole) for benzene, C₆H₆ needs to be determined.

Concept introduction:

For a general reaction as follows:

$\text{reactant}\to \text{products}$

The value of change in enthalpy of the reaction can be represented as follows:

$\Delta {\text{H}}^{\circ }{}_{\text{reaction}}\text{=}{{\displaystyle \sum \Delta H^{\circ }{}_f}}_{\text{products}}-{{\displaystyle \sum \Delta H}}^{\circ }{{}_f}_{\text{reactant}}$

Here, $\Delta H^{\circ }{}_f$ is change in standard enthalpy of formation.
