Answer:
Fast and slow free-radical recombination reactions in thermal breakdown. As thermally induced bond-cleavage reactions and the depolymerisation of coals accelerate above 350–375°C, the more reactive of the free radicals have greater potential to undergo either retrogressive or quenching (cappin
Explanation:
Bond cleavage, or bond fission, is the splitting of chemical bonds. This can be generally referred to as dissociation when a molecule is cleaved into two or more fragments.
