Many animations: measurement of rates; effect of concentration, temp, surface area, catalysts. A fun interactive whiteboard quiz hosted by Mister T; a chance for pupils to interpret a rate of reaction graph. Some of the excellent animations are free samples from Crocodile Clips Chemistry (see link below). Some are from the excellent www.sciencepages.co.uk who kindly gave permission for their use.

If you use this resource take care and change the audio file as when pressed it uses the word F**K

A brilliant resource! It contains many high quality animations, chances for interactivity, and is very well structured with a good level of detail. The quiz is also excellent, including sound effects!

A well structured resource with slides that are clear and not overly fussy. The material can be presented clearly to the class.

Just to clear things up, this resource does not contain swearing, but one of the sound effects is a cartoon-style 'you suck' which could be misheard. There is some edgy humour in here (e.g. using acid to dispose of a body) so only download if you think this will suit your class. If you are using PowerPoint 2007, you need to save the file, open in normal view and then click on the security warning just above the slide to enable active content.

Understanding Rates of Reactions

1Understanding Rates of ReactionsUse the green button to advance slides that contain animationshttp://teachable.net/res.asp?r=10152What takes part in a reaction?Reactants These are the chemicals that react together (on the left side of the chemical equation)
Products These are the chemicals that get made in the reaction (on the right side of the equation)
Sometimes there may only be one reactant or one product. Can you think of an example?3Copper + Oxygen ? Copper oxide
Copper oxide + Sulphuric acid ? Copper sulphate + Water4Particles and CollisionsParticles need to hit each other (collide) to react
Anything that makes particles collide more often will speed up a reaction
Faster collisions have more energy so they are more likely to react together5Measuring the Rate of a ReactionYou can measure how fast a reaction produces a gas6Measuring the Rate of a ReactionYou can measure how fast a reaction loses mass (when a gas is given off)
Notice how both the reactions
