Question
![In a study of the conversion of methyl isonitrile to acetonitrile in the gas phase at 250 °C:
\[ \text{CH}_3\text{NC(g)} \rightarrow \text{CH}_3\text{CN(g)} \]
the concentration of CH₃NC was followed as a function of time.
It was found that a graph of \(\ln[\text{CH}_3\text{NC}]\) versus time in seconds gave a straight line with a slope of \(-4.77 \times 10^{-3} \, \text{s}^{-1}\) and a y-intercept of \(-3.86\).
Based on this plot, the reaction is _____ order in CH₃NC and the rate constant for the reaction is _____ s⁻¹.
### Explanation:
The dropdown menu includes options for "zero," "first," and "second" to determine the order of the reaction. The slope of the line indicates the rate constant for the reaction when the graph of \(\ln[\text{CH}_3\text{NC}]\) versus time is a straight line, implying a first-order reaction process.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe19fa2ed-8566-4b3b-96d0-3591866fab62%2F060a88e2-114c-4f94-89f9-c8a171870774%2F8m7u6ap_processed.png&w=3840&q=75)
