Understanding the relationship between Kc and Kp
We can derive a value for the equilibrium constant in a gaseous equilibrium system either using partial pressures, Kp, or

Calculating Kp, the equilibrium constant, for a gaseous system.
For reversible reactions taking place in the gaseous phase it is more straightforward to think in terms of pressure rather

Why don’t reactions at equilibrium go to completion?
To complete our understanding of systems that have achieved equilibrium, we need to look at the position of equilibrium through

How to find the equilibrium constant and equilibrium concentrations for a reaction
Now it is time to introduce the concept of the equilibrium constant, Kc. Kc is basically a ratio – the

What is le Chatelier’s Principle?
When we have a chemical reaction that has reached a state of dynamic equilibrium, there will be one particular set
What is position of equilibrium?
I’m sure you will all have seen a strip of magnesium burning in a Bunsen burner flame. It is a
Elimination reactions – dehydrating an alcohol
If we dehydrate an alcohol, we are essentially removing a water molecule and the product will be an alkene. The

Electrophilic addition in alkenes (3) – reaction with water to form an alcohol
The reaction of an alkene with water to from an alcohol is an example of a hydration reaction. The alkene

Electrophilic addition in alkenes (2) – the bromine water test
The classic test for an alkene is to shake your sample with orange bromine water, and if the molecule contains

Making addition polymers by radical polymerisation
The mechanism for addition polymerisation is another example of a radical reaction. Teflon (PTFE), famously known for its non-stick properties,
