How does concentration affect the rate of a reation In this experiment I will have to look at how concentration affects the rate of reaction. I will have to decide which concentrations to change, and the reaction that I will be performing. Prediction The reaction I have chosen is: Sodium + Hydrochloric ==> Sulphur + Sodium + Sulphur + Water Thiosulphate + Acid Chloride Dioxide Na2S2O3 (aq) + HCL (aq) ==> S(s) + 2NaCl (aq) + SO2 (g) + H2O (l) There are many different things I can change which will affect the rate of reaction, so I will have to do preliminary experiments to find out ideal quantities for my final experiment. Below are some variables I can change for my experiments: o Temperature o Concentration of Sodium Thiosulphate o Concentration of Hydrochloric Acid o Volume of Sodium Thiosulphate o Volume of Hydrochloric Acid o If I stir the experiment or let it stand For this reaction I will have to decide a...
