How does the concentration of the reactants affect the rate of reaction when sodium thiosulphate and hydrochloric acid are combined? Introduction: A chemical reaction is a process in which one set of chemical substances, known as the reactants, are changed into another substance or set of substances, called the products. The factors that affect the rate of chemical reactions include: * Particle size. * The use of a catalyst * Concentration. * Pressure. * Temperature. For my investigation I have chosen to analyse the way in which the rate of reaction is altered by the concentration of the reactants. When the reactants, sodium thiosulphate and hydrochloric acid, are combined they produce 4 different products as shown in the following equation: Sodium Thiosulphate + Hydrochloric Acid --> Sodium + Water + Sulphur + Sulphur Chloride Dioxide Na2S2O3 (aq) + 2HCl (aq) --> 2NaCl (aq) + H2O (l) + SO2 (g) + S (s) In my experiment I intend to change...
