Chemistry Coursework Rate of reaction Aim: Plan an investigation into the rate of reaction between Sodium thiosulphate and hydrochloric acid. Background information: • The equation for the rate of reaction is 1/time. • The rate of reaction measures the speed of reaction. It is a measure of the loss of reactants and gain of products. • The faster a reaction takes place, the shorter the time needed for the reaction to finish. • An example of a slow reaction …showed first 75 words of 1212 total…

…showed last 75 words of 1212 total…other variables that can be investigated which can affect the rate of reaction. They are: pressure, light, catalysts and particle size. In conclusion my results are sufficient enough to prove that the collision theory is correct. The reliability of this investigation is suitable enough to support a firm conclusion that the rate of reaction speeds up if the concentration of a solution is higher. This has been proven by my experiment and the collision theory.
