What is order and molecularity of following reaction?
\(\mathrm{NO}_{2(\mathrm{~g})}+\mathrm{NO}_{2(\mathrm{~g})} \longrightarrow 2 \mathrm{NO}_{(\mathrm{g})}+\mathrm{O}_{2(\mathrm{~g})}\)
- A order 1, molecularity 2
- B order 2, molecularity 2
- C order 2, molecularity 3
- D order zero, molecularity 2
Answer & Solution
Correct Answer
(B) order 2, molecularity 2
Step-by-step Solution
Detailed explanation
Molecularity \( = 1+1 = 2 \). Order \( = 1+1 = 2 \) (assuming it is an elementary reaction).
