The rate followed first order kinetics in [CAT] and [Hydrazide]. Effects of externally added reaction products and NaCl had no effect on the reaction. Effects of change in the dielectric constant and pH of the reaction medium on the rate have been also investigated. The rate constants for the rate-controlling step have been calculated as functions of temperature. The activation parameters have been computed using these constants. The mechanism in which chloramine-T reacts with hydrazides giving acyldiimide as an intermediate in the slow and rate-determining step has been proposed.
