Description

One of the most important laws in chemistry is the mass action law. On the basis of the mass action law the rate of a chemical reaction is directly proportional to the product of the activities or concentrations of the reagents, which means that for a chemical reaction mixture that is in equilibrium, the ratio between the concentration of reagents and products. There are two aspects in the law, first the equilibrium aspect, regarding the composition of a reaction mixture at equilibrium and second the kinetic aspect regarding the rate equations for elementary reactions. During this work we tried to introduce to achieve an empirical description of the rates of chemical reactions on a macroscopic level and to relate the laws describing those rates to mechanisms for reaction on the microscopic level though react between reagents sodium thiosulfate with sulfuric acid. In experimentally way, it’s tried to find the depending of rate of a reaction in change the temperature and the concentrations of the reactants and products. This paper presents the dependencies of the reaction speed by changing the concentration and by changing the temperature experimentally by using the differential rate of reaction. The results are presented in table and graphical forms.
