Delve into the fascinating world of thermochemistry, where we explore how heat is involved in chemical reactions and changes in state. This section covers the principles of heat transfer, enthalpy changes, and calorimetry. Learn to calculate reaction heat changes, understand exothermic and endothermic processes, and apply Hess's Law to determine reaction energies. We will also discuss the relationship between thermochemistry and reaction spontaneity, providing insights into the energetic aspect...

CHEM 103 MODULE 3 NOTES. 3.1: THERMOCHEMISTRY Thermodynamics is the study of the relationship between heat and other forms of energy, particularly mechanical work. Thermochemistry is the part of thermodynamics that deals with the quantity of heat given off or absorbed during a chemical reaction. The quantity of heat given off or absorbed during a physical change or temperature change can also be studied, and we will refer to this process as calorimetry. In order to adequately discuss thermoch...
