Chapter 9, Problem 15SAQ

Interpretation Introduction

Interpretation:

“Enthalpy of reaction” should be explained.

Concept introduction:

Enthalpy of reaction can be determined by subtraction of enthalpy of formation of reactant from enthalpy of formation of product can be shown as follows:

ΔH_rxn = ΔH_product − ΔH_reactant

Given:

ΔH_H2O = −242.6 kJ/mol

ΔH_CH3CH2CI = −139.2 kJ/mol

ΔH_CH3CH2OH = −277.7 kJ/mol

ΔH_HCI = −92.4 kJ/mol
