Final answer:
The chemical reaction for the formation of 2NOBr(g) from 2NO(g) and Br₂(g) is 2NO(g) + Br₂(g) → 2NOBr(g), showing a redox process and chemical equilibrium.
Step-by-step explanation:
The chemical reaction for the formation of 2NOBr(g) from 2NO(g) and Br₂(g) is represented by the following balanced equation:
2NO(g) + Br₂(g) → 2NOBr(g)
This equation indicates that two molecules of nitrogen monoxide gas react with one molecule of bromine gas through a redox process to form two molecules of nitrosyl bromide gas. The double arrow in the reaction shows that this reaction can occur in both the forward and reverse directions under certain conditions, which is characteristic of a chemical equilibrium.
