Year 11 Chemistry

Module 4 | Drivers of reactions

Content 1: Energy changes in chemical reactions

Lesson 1 | Endothermic and exothermic reactions

• conduct practical investigations to measure temperature changes in examples of exothermic and endothermic reactions including:
  – combustion
  – dissolution of ionic substances in aqueous solution (ACSCH018, ACSCH037)

Lesson 2 | Enthalpy changes

• investigate enthalpy changes in reactions using calorimetry and q = mc$\Delta$T (heat capacity formula) to calculate, analyse and compare experimental results with reliable secondary-sourced data, and to explain any differences

Lesson 3 | Energy profile diagrams

• construct energy profile diagrams to represent and analyse the enthalpy changes and activation energy associated with a chemical reaction (ACSCH072)

• model and analyse the role of catalysts in reactions (ACSCH073)
