Which outcome reduces the rate of a chain reaction?

💡 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.
