Abstract
The kinetics of the oxidation of cuprous chloride with oxygen was studied in the solution of hydrochloric acid whose concentration range was 0.2-4.8 molg. Since the reaction was fairly fast, it was difficult to study the reaction by the ordinary kinetic method. Accordingly, the reactions li'vere observed in a stirred vessel with a flat gas-liquid interface in the diffused state. The observed chemical absorption rates of oxygen were analyzed by using the equations for chemical absorption obeyed (m+ n) th-order irreversible kinetics, and it was found that the reaction was of the first-order with respect to cuprous chloride and oxygen. The over-all reaction rate constants were determined from the experimental data by using the equations for chemical absorption obeyed second-order kinetics. It was found that cupric chloride in the solution retarded the reaction rates. The retardation due to cupric chloride was studied and found that the concentration of cuprous chloride was decreased due to the formation of a complex with cupric chloride, which brought about the depression of the rate.
