The following data is obtained during the first order thermal decomposition of
\(2 \mathrm{~A}(g) \longrightarrow \mathrm{B}(g)+\mathrm{C}(\mathrm{s})\)
at constant volume and temperature.
The rate constant in \(\min ^{-1}\) is
- A \(0.0693\)
- B \(6.93\)
- C \(0.00693\)
- D \(69.3\)
Answer & Solution
Correct Answer
(A) \(0.0693\)
Step-by-step Solution
Detailed explanation
\(2 p-x+x+x=300\) (given)
\(2 p+x=300\)
\(\therefore \quad \mathrm{x}=300-200=100\)
\(\mathrm{k}=\frac{2.303}{10} \log \frac{200}{100}\)
\(=0.0693 \mathrm{~min}^{-1}\)
