✦ Synopsis

A differential method for analyzing first-order kinetic data is presented. While the essence of this approach has been known for almost a century, the use of computers to collect, store, and manipulate data has reenergized this innovative idea. Based on the equation ln dA t /dt ϭ ln k(A o Ϫ A ϱ ) Ϫ kt, plots of ln dA t /dt vs. t were found to be linear for both simulated kinetic data and data collected for the reaction of [(en) 2 Co(SCH 2 CH 2 NH 2 )] 2ϩ with acrylamide. The rate constants for the reaction obtained by this method are identical to those obtained by the infinite-time method of analysis, but do not require infinite-time measurements in their evaluation.
