Kinetics and Mechanism of oxidation of DL-Aspartic Acid by Chromic Acid in presence of Hydrochloric Acid has been carried out at 29^oC. The reaction is first order with respect to (DL-Aspartic Acid) & (Chromic Acid) and the total order is two. The order of reaction with respect to [H+] ion is also one. Ostwald isolation method is used for study of rate of reaction. The probable products are acetaldehyde, CO₂ & ammonia. Mechanism involving C-C fission has been suggested. The rate of reaction increases with increase in the Hydrochloric Acid concentration in the system. The rate constant has been computed by first order reaction. The pH value, Catalytic constant and temperature coefficient have also been determined for all the runs. On the basis of experimental findings, the proposed rate expression is. -d [Cr(VI)] = k [ Cr (VI)] [DL-Aspartic Acid] [H⁺] dt
