Introduction to Entropy and Gibbs Free Energy

Enthalpy vs Entropy

This post will introduce the first dot point of the final topic for Prelim Chemistry which is about entropy and Gibbs free energy.

Topic: Entropy and Gibbs Free Energy

  • Analyse the differences between entropy and enthalpy
    • Use modelling to illustrate entropy changes in reactions

 

What is Entropy?

Entropy describes the level of disorder in a system. Things will always go towards greater disorder, for example think of your room (unless you are very tidy), you clean it but then after 2 weeks you find yourself again in a messy room. This video introduces the concept of entropy.

 

This video goes through entropy in a little more detail.

 

Enthalpy vs Entropy

Recall the definitions of both, enthalpy refers to the energy of bonds in a molecule while entropy describes the level of a disorder of a system. This video goes through more detail about the differences between enthalpy and entropy.
