Resumo: Infinity readings for first order kinetics can be calculated from any three measurements (triads) of a physical property l at three equallyspaced times. Accurate results can be obtained from time intervals aslow as 0.4 half-life. Calculation of infinity readings l¥ from severaltriads at increasing values of time gives an insight into the deviation of the first order kinetics when parallel, consecutive or other spurious reactions occur along with the main first order reaction, not allowing direct measurements or calculation of l¥. The proposed method is more sensitive in distinguishing between first and second order kinetics than the Guggenheim and Kezdy-Swinbourne methods.
