Step 1
What is the oxidising agent in this reaction?
Answer
To determine the oxidising agent in this reaction, we need to understand what oxidation and reduction mean. An oxidising agent is a substance that gains electrons and, in the process, causes another substance to be oxidised.
In the given reaction:
we can observe that nitrogen monoxide (NO) reacts with oxygen (O2) to form nitrogen dioxide (NO2). Here, oxygen is the species that gets reduced, meaning it gains electrons, while nitrogen monoxide is oxidised as it loses electrons to form nitrogen dioxide.
Thus, the oxidising agent in this reaction is oxygen, making the answer:
D. Oxygen
