Final answer:
During hydrogen oxidation, the consumption of OH in the formation of water produces an H atom, which continues the chain reaction. This step is called a chain propagation reaction.
Step-by-step explanation:
The process described in the question is an example of a chain propagation reaction in the context of hydrogen oxidation. During this reaction, the OH radical is consumed to form a stable water molecule, and as a result, an H atom is produced. This H atom can then continue the chain reaction, allowing the overall reaction sequence to continue without increasing the number of highly reactive species.
