RATES of REACTION - revision notes INDEX

Doc Brown's Chemistry science GCSE 9-1, IGCSE & O level Revision Notes - Doc Brown's chemistry revision notes: basic school chemistry science GCSE chemistry, IGCSE  chemistry, O level & ~US grades 8, 9 and 10 school science courses or equivalent for ~14-16 year old science students for national examinations in chemistry

1. What do we mean by the rate/speed of reaction? An INTRODUCTION to REACTION RATES

Why is it important to know how fast reactions occur?

How can we measure the speed or rate of a chemical reaction?

Experimental methods are described in this introduction & subsequent sections

2. Collision theory of chemical reaction rate factors A general introduction, then applied to sections 3a to 3e

3. Factors affecting the speed/rate of a chemical reaction:

3a Effect on rate of changing reactant concentration in a solution/gas mixture

3b Effect on rate of changing pressure in reacting gases (gaseous equivalent of 3a)

3c Effect on rate of changing particle size/surface area & stirring of a solid reactant

3d Effect on rate of changing the temperature of reactants

3e Effect on rate of using a catalyst in a chemical reaction

Activation energy and reaction profiles  and for enzymes - natural biochemical catalysts

Enzymes - biological catalysts, optimum pH or temperature, use in biotechnology (GCSE chemistry)

Enzymes - structure, function, optimum conditions, investigation experiments (GCSE biology notes)

3f Light initiated reactions - effect of changing intensity

4. Examples of graphs of rate data, interpretation a summing up of ways your rate data can be analysed and interpreted

Sections 5 to 7 are for Advanced A Level Chemistry Students ONLY

Some ideas to help you with RISK ASSESSMENT when designing and performing 'Rates of Reaction' experiments and many other experimental procedures. Some aspects listed are applicable to 'rates/kinetics' assignments, others are not applicable at all. Its up to you to decide!
