Aim: To investigate the factors affecting the rate of any reaction. Research question: To investigate the effect on the rate of reaction on adding different concentrations of Sodium thiosulphate and Hydrochloric acid, (for the formation of sulphur ). Further determining which reactant( s) affect the rate of formation of sulphur( rate of reaction ). And through this experiment to determine the order of the reaction between sodium thiosuplhate, hydrochloric acid. Hypothesis: Theoretically, the concentration of both the reactants affect the formation of sulphur, and Introduction: Variables and constants
