Chemistry Paper 2 - Rates of Reaction

Here is a little look at rates of reaction and the scientific key words you should be using. When talking about increasing temperature the key word is kinetic energy. If you’re looking at concentrations 2M is a higher concentration than 0.5M because there more particles in the same volume. Also, what about surface area: the smaller the pieces (like powder) the more surfaces. Let’s not forget about catalysts. They are chemicals that lower the activation energy to speed up chemical reactions.
