The kinetic study or Ce^IV oxidation or maltose and lactose fa aqueous sulphuric acid medium shows first order kinetics with respect to both Ce^IV as well as substrate. The reaction rate decreases on increasing the concentration or hydrogen ion. The sulphate ion shows retarding effect on reaction rate. The values of activation energy have been calculated and a suitable mechanism conforming to the kinetic data is proposed.
