Waleed Mahmood Chemistry Coursework Rates of Reaction Sodium Thiosulphate and Hydrochloric acid In this piece of coursework, I will study how concentration affects the rate of reaction. I will do so by timing the reaction of Sodium Thiosulphate with an acid. In this coursework, I will include background knowledge, prediction, safety, results, calculations, graphs, an analysis, conclusion and an evaluation. In my evaluation I will comment on how reliable my results were and how I could have improved my coursework in any possible way. The definition of rate of reaction is 'The speed at which a chemical reaction takes place'. The factors that affect the rate of reaction are: * Use of a catalyst * Temperature * Surface area * Concentration I will be investigating Concentration in this experiment. In a higher concentration there are more Sodium Thiosulphate particles. This means there is a higher number of collisions which will have enough energy to react. This causes the rate to...
