Only a tenuous link with chemistry (kinetics is about movement) but click on this image to enlarge it, and it will look like it is moving when it actually isn’t.
Kinetics is all about the rate at which chemical reactions happen and the factors that govern this. At SL, this means consolidating the understanding of collision theory gained at IGCSE-level, and then extending this to understand how the ‘Boltzmann distribution’ is able to explain the effects of temperature on rate in greater depth than collision theory on it’s own. At HL we develop a quantitiative framework for analysing reaction rates, learning to develop rate equations, and understanding how these give us valuable insight into the internal mechanisms behind chemical reactions.
Presentation:
You are strongly encouraged to use this in lessons, and make notes on it. Used in conjunction with the experiments and other activities it more or less contains everything you need to know. This can be viewed on most laptops, smart phones and tablets!
