Learning Area: 

In Term 1.2, we will conclude our studies of some important questions across a broad range of topics in chemistry:

1. How can we speed up or slow down chemical reactions for useful purposes? What are some cool examples and contexts where this is applied?
2. What is dynamic equilibrium, and why is this useful in everyday life, from keeping the world's oceans' pH stable to producing fertiliser to feed the world's rapidly growing population?
3. What are acids and bases, and what are their properties?

Through learning these three topics (rates of reaction, dynamic equilibrium, and acids and bases), students will be prepared for an external assessment worth 4 credits (AS91166).

Contexts: Rocketry, ocean acidification

Essential vocabulary: reaction rate, collision theory, activation energy, catalyst, surface area, temperature, enthalpy change, reversible reaction, dynamic equilibrium, closed system, Le Chatelier's principle, Lewis acids, Lewis bases, dissociation, weak vs strong, dilute vs concentrated, indicator, pH
