What is the order of reaction for decomposition of gaseous acetaldehyde?
- A 1
- B 2
- C \(1.5\)
- D 0
Answer & Solution
Correct Answer
(C) \(1.5\)
Step-by-step Solution
Detailed explanation
Decomposition of gaseous acetaldehyde,
\(\mathrm{CH}_{3} \mathrm{CHO}_{(\mathrm{g})} \longrightarrow \mathrm{CH}_{4(\mathrm{~g})}+\mathrm{CO}_{(\mathrm{g})}\)
\(\therefore\) Rate \(=\mathrm{k}\left[\mathrm{CH}_{3} \mathrm{CHO}\right]^{3 / 2}\)
The order of the reaction is \(1.5\)
\(\mathrm{CH}_{3} \mathrm{CHO}_{(\mathrm{g})} \longrightarrow \mathrm{CH}_{4(\mathrm{~g})}+\mathrm{CO}_{(\mathrm{g})}\)
\(\therefore\) Rate \(=\mathrm{k}\left[\mathrm{CH}_{3} \mathrm{CHO}\right]^{3 / 2}\)
The order of the reaction is \(1.5\)
