- C Reaction of \(\mathrm{H}_{2} \mathrm{SO}_{4}\) with \(\mathrm{NaOH}\)
- D Reaction of \(\left[\mathrm{Co}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right] \mathrm{Cl}_{3}\) with \(\mathrm{AgNO}_{3}\)
Answer & Solution
Correct Answer
(A) Combination of dinitrogen with dioxygen at \(2000 \;K\)
Step-by-step Solution
Detailed explanation
\(\mathrm{N}_{2}+\mathrm{O}_{2} \stackrel{2000 \mathrm{K}}{\longrightarrow} 2 \mathrm{NO} \quad\) (Redox reaction) during the reaction, oxidation of nitrogen take place from \(0\) to \(2\) and reduction of oxygen take place from \(0\) to \(-2 .\) It means this reaction is redox…
