Course Work (1) Rates of Reaction Planning I am planning to do an experiment to investigate how varying concentration affects the rate of reaction. I intend to do this by collecting the following equipment, stop clock, safety goggles, apron, conical flask, paper with a cross on it, thermometer and chemicals sodium thiosulphate and hydrochloric acid. -Then I will wear the safety equipment and measure 50ml of sodium thiosulphate and 5ml of hydrochloric acid (in a different measuring cylinder). -Then I am going to mix the chemicals in a conical flask that is on top of the paper. I will time how long it takes to make the cross disappear. -I will repeat the above steps, 3 times for 5 different concentrations, recording both concentration and time for each one. I think that the higher concentrations will do the reaction more quickly than the lower concentrations. This is because I know that the higher concentrations have got more 'parts'...
