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.

Static and Dynamic Equilibrium

Inquiry question: What happens when chemical reactions do not go through to completion?

Factors That Affect Equilibrium

Inquiry question: What factors affect equilibrium and how?

Calculating Equilibrium Constant

Inquiry question: How can the position of equilibrium be described and what does the equilibrium constant represent?

Solution Equilibria

Inquiry question: How does solubility relate to chemical equilibrium?

Dissociation of Acids and Bases
