Module 4 – Drivers of Reaction

 

Module 4: Drivers of Reaction is the fourth module of Year 11 HSC Chemistry.

Energy Changes in Chemical Reactions

Inquiry question: What energy changes occur in chemical reactions?

• Enthalpy Change, Activation Energy, Catalysts & Temperature

• ΔH of Combustion and Neutralisation, Calorimetry

Enthalpy and Hess's Law

Inquiry question: How much energy does it take to break bonds, and how much is released when bonds are formed? 

• Enthalpy Change (ΔH) in Ionic Compound Dissolution

• Calculating the Enthalpy of Formation

• Hess's Law

Entropy and Gibbs Free Energy 

Inquiry question: How can enthalpy and entropy be used to explain reaction spontaneity?

• Entropy and Gibbs Free Energy (ΔG)
