2.4 Kinetics of second-order reactions 27 I Figure 2.10: Kinetics of pseudo first-order reactions. 2.4.4 Comparison of first-order and second-order reactions Consider a first-order and a second-order reaction with the same initial concentrations and the same initial rate at = 0. As shown in Fig. 2.11 below, the rate of the second-order reaction rapidly slows down as time increases. I Figure 2.11: Comparison of first-order and second-order reactions.
2.5 Kinetics of third-order reactions 28 2.5 Kinetics of third-order reactions y A+B+C→ D (2.98) − [A] = [A] [B] [C] (2.99) I Pseudo second-order combination reactions: In combination reactions of two species A + A → A 2 or A + B → AB (for example, the recombination of two free radicals), one of the species (bath gas M) is usually present in large excess ([M] À [A], [B]), so that the kinetics becomes pseudo second-order, giving the two cases: • • A+A+M→ A 2 +M (2.100) A+B+M→ AB + M (2.101) M plays the role of an inert collision partner which removes the excess energy from the newly formed A 2 or AB molecules.
