Factors affecting the Speed-Rates of Chemical Reactions
These pages describe the factors controlling the speeds of chemical reactions and the collision theory behind it discussed. The factors affecting the speed of reaction are also presented using particle models to give a theoretical basis to the rules on the effects of concentration, pressure, temperature, solid reactant particle size (surface area), stirring, catalysts and light. Methods of how to collect data are also described and graphical treatment of the observations and how to draw conclusions. How do we graphically interpret tables of results and what graphs are useful and why. How to we calculate the speed of a reaction? These pages should also prove useful for coursework projects on rates/speeds of reactions e.g. help with ideas, apparatus, experimental methods, product collection, reaction equations and calculations etc. These revision notes are suitable for GCSE IGCSE O Level KS4 science chemistry students studying the factors that control the rate or speed of a chemical reaction. The descriptions of experiments to do with ...and theoretical explanations should help with homework, coursework assignments, 'labs' on rates of reaction experiments - anything to with the speed of chemical reactions and their controlling factors.
