Competition Kinetics of the Nonbranched-Chain Addition of Free Radicals to Olefins, Formaldehyde, and Oxygen

Scheme 1

Chain initiation:
(1) I 2 𝑘 1 − − → 2 R • 0 ;
(1a) R • 0 + R 1 A 𝑘 1 a − − → R 0 A + R • 1 ;
(1b) R • 0 + R 2 B 𝑘 1 𝑏 − − → R 0 B + R • 2 .
Chain propagation:
(2) R • 1 + R 2 B 𝑘 2 − → R • 3 ;
(3) R • 3 + R 1 A 𝑘 3 − → R 3 A + R • 1 .
Inhibition:
(4) R • 3 + R 2 B 𝑘 4 − → R 3 B + R • 2 .
Chain termination:
(5) 2 R • 1 2 𝑘 5 − − → P r o d ;
(6) R • 1 + R • 2 𝑘 6 − → P r o d ;
(7) 2 R • 2 2 𝑘 7 − − → P r o d .
