← ScienceWhich outcome reduces the rate of a chain reaction?
A)Radical scavenging by inhibitor reaction✓
B)Increased concentration of chain carriers
C)Higher initiation rate constant
D)Thermal runaway escalating propagation rate
💡 Explanation
Radical scavenging lowers the rate because it reduces the concentration of radicals via inhibitor reactions. The inhibitor stops propagation by combining with chain propagating radicals, therefore, fewer radicals are available to sustain the chain reaction, rather than continuing at increasing rates.
