Chemical Energetics: Enthalpy, Entropy and Gibbs Free Energy

Learn the entire A Level Chemical Energetics (with a focus on ∆H, ∆S, and ∆G). This course is written based on the Singapore A Level Chemistry syllabus (9729).

In this course, we will cover:

Enthalpy change (∆H)

- Definition of the various enthalpy changes (i.e. combustion, reaction, formation, neutralisation, atomisation, hydration, solution)

- Lattice energy

- Bond energy and bond dissociation energy

- Using bond energy values to calculate the enthalpy change

- Hess Law

- Drawing of energy cycles to calculate unknown enthalpy changes

- Drawing energy level diagrams

- Drawing Bond Haber Cycle and applying it to questions involving lattice energy

- How to find enthalpy change experimentally, and how to use data from experiments to find an unknown enthalpy change (∆H).

Entropy change (∆S)

- What affects entropy change

- Predicting if a change results in an increase or decrease in entropy

Gibbs Free Energy change (∆G)

- What is Gibbs Free Energy change, and calculating Gibbs Free Energy

- How Gibbs Free Energy is related to enthalpy change, entropy change and temperature

- Predicting whether the reaction is spontaneous or not using Gibbs Free Energy change

- limitations of using Gibbs Free Energy change to predict reaction

This is the course that I conduct in my face-to-face tuition lessons. The complete course usually takes multiple 2- hour lessons. But now, you can learn the entire chemical energetics anytime, anywhere, at your own pace, and watch it any number of times you like.
