For the decomposition of azomethane. \(CH _{3} N _{2} CH _{3}( g ) \rightarrow CH _{3} CH _{3}( g )+ N _{2}\) (g) a first order reaction, the variation in partial pressure with time at \(600\,K\) is given as
- A \(1\)
- B \(2\)
- C \(3\)
- D \(9\)
Answer & Solution
Correct Answer
(B) \(2\)
Step-by-step Solution
Detailed explanation
For first order reaction \(k =\frac{1}{ t } \ln \left(\frac{ P _{0}}{ P }\right)\) \(\ln \left(\frac{ P _{0}}{ P }\right)= kt\) \(t _{1 / 2}=\frac{\ln 2}{ k }=\frac{0.693}{3.465 \times 10^{4}}=2 \times 10^{-5}\)
