Department of Chemistry, Nagpur University, Nagpur Manuscript received 28 April 1971; revised 1 August 1972; accepted 1 December 1972 The reaction of malate with aqueous iodine is slow in the absence of Mn (VII). Manganese (VII) increases the rate of reaction. The induction factor, (I2)/(Mn(VII) ) of this reaction at pH-4.15 is found to be less than unity (i.e., 0.5). The rate increases with the increase in malate and Mn (II) concentration, temperature and pH. First order rate constants
