Chemistry practical coursework As we all know some reactions happen very quickly (e.g. rubidium in water) and on the other hand some happen very slowly (and iron nail in water). Therefore the only way of measuring the rate of a reaction is by performing an experiment. For this experiment to work I will have to work out a way of measuring either i) the rate at which reactants are used up in a reaction (most likely to be magnesium) or ii) the rate at which products are formed in a reaction (most likely to be hydrogen). I will have to experiment on one variable which affects the rate of reaction, but on the other hand keep all other variables the same, including the chronological order in which the experiment is done. The rates of reaction are all dependant on the collision theory and this is what I will use to explain how...
