What Is Thermochemistry?

Definition and Scope

Thermochemistry is a branch of chemistry that deals with the study of heat transfer during chemical reactions and physical transformations. It integrates principles from thermodynamics and chemistry to analyze energy changes at the molecular level.

Core Concepts in Thermochemistry

• Enthalpy (ΔH): The heat content of a system at constant pressure.
• Heat of Reaction: The amount of heat absorbed or released during a chemical reaction.
• Specific Heat Capacity: The amount of heat required to raise the temperature of a substance per unit mass.
• Hess’s Law: The total enthalpy change for a reaction is the same, no matter how it occurs in steps.
• Calorimetry: The experimental measurement of heat transfer in physical and chemical processes.

Role of Pearson Education in Teaching Thermochemistry
