Building upon our previous discussions of thermochemistry, enthalpy, entropy, heat capacity, and calorimetry, this episode focuses on Hess's Law. Hess's Law is a fundamental principle that allows us to calculate the enthalpy change for a reaction that may be difficult or impossible to measure directly. We will explore the concept that enthalpy is a state function, the core principle behind Hess's law, and learn how to manipulate and combine known enthalpy changes of other reactions to determine the enthalpy change of the target reaction. This episode is essential for mastering thermochemical calculations and predicting the energy changes in complex chemical processes. It will form the basis of your understanding for future lessons, such as Gibbs Free Energy.

In this episode, we introduce Gibbs free energy, a powerful concept that answers this very question. Building on our understanding of enthalpy from Hess's law and calorimetry, we'll explore the missing piece of the puzzle: entropy, the measure of disorder. You'll learn how the Gibbs free energy equation combines the drive for lower energy (enthalpy) and higher disorder (entropy) to predict whether a reaction will be spontaneous. This episode will equip you with the ultimate tool for forecasting chemical change.
