Chemistry class is now in session

Let’s find out about Introduction to Equilibrium (Module 5: Year 12 HSC Chemistry)

We’re back again with another video series, hosted by our Talent 100 Academic Director Dr Nikhil Vasan! We’re going to break down a few of the most important topics for each section of Module 5: Equilibrium and Acid Reactions for HSC Chemistry (Module 5).

Let’s get a head start into HSC Chemistry Module 5, and look into the foundations of equilibrium.

We’re all used to chemical reactions in one direction, but did you turn up to your HSC Chemistry class and one day and see this ⇌ sign? It’s all about Equilibrium! Not only is equilibrium an important concept of Module 5 (Equilibrium and Acid Reactions), but this is going to be a huge part of everything you’re going to learn in Chemistry from here on out.

Equilibrium Reactions

In Chemistry so far, you’re probably used to seeing reactions that go in one direction. For example, combustion reactions or photosynthesis reaction. Have a look at this middle arrow, see how it’s in one direction and just going to the right:

All of the chemical reactions you’ve probably seen so far would actually look like this. It indicates that the two substances on the left, has reacted together and formed the substances to the right of the arrow and there’s no going back. But, most reactions in chemistry actually don’t work like this.
