Module 5 - Equilibrium and Acid Reactions

Module 5: Equilibrium and Acid Reactions is the first module of the new NSW HSC Chemistry curriculum.

In this module, students explore the nature of reversible reactions while building upon their knowledge from Year 11 Chemistry. This includes ideas such as enthalpy, entropy, Gibbs free energy as well as various types of chemical reactions.
