Red + green represent reactants and blue + purple represent products
Fruitful collisions =
chemical change, if only it were that simple, lots of factors to consider! 1. An INTRODUCTION to REACTION RATES What do we mean by the rate/speed of reaction? 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 (gas equivalent of 3a) 3c Effect on rate of changing particle size/surface area, stirring mixture of a solution-solid reactant 3d Effect on rate of reacting on changing the temperature of reactants 3e Effect on rate of reaction using a catalyst in a chemical reaction
3f Light initiated reactions - effect of changing intensity GCSE Level MULTIPLE CHOICE QUIZ on RATES of reaction Sections 5 to 7 are for Advanced Level Chemistry Students ONLY (separate page) 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! What next?
