It is equal to the reciprocal of the sum of the first‐order rate constants of all processes causing the decay of the molecular entity. 2.1.9 Lifetime ( τ) For a molecular entity that is reacting by first‐order kinetics, ( τ) is the time required for its concentration to decrease to 1/ e (≈0.37) of its initial value. This term is commonly used in the so‐called lifetime methods, such as NMR, in relaxation methods, such as temperature jump, and in the kinetics of decay of electronically excited states. If the concentrations of reactants are not in their stoichiometric ratios, the half‐lives for the different reactants are not the same and use of the term half‐life of the reaction is not warranted. Statistically, it represents the life “expectancy” of the entity. Chemical kinetics and reaction mechanisms espenson pdf the best free software f.
