Entropy – Embrace the Chaos

Everything tends towards disorder” or so they say…

So let’s take a look at how entropy, enthalpy and temperature combine to help us understand if a reaction is spontaneous or not!

Gibbs’ Free Energy is yet another formula / calculation that you are expected to remember for your A Level Chemistry exam.

OK, so remembering it isn’t that hard, but being able to understand where it comes from and qualitatively explain how and why it works is another.

It’s really important you understand it as the exams may give you follow-up questions based on this formula asking you to explain the changes.


Another great explanation here from “Crash Course Chemistry” for you to get your teeth into that take time to explain how it all comes together.
