Chapter , Problem 21E(choose chapter or problem)
The isomerization of methyl isonitrile \(\left(\mathrm{CH}_{3} \mathrm{NC}\right)\) to acetonitrile (\left(\mathrm{CH}_{3} \mathrm{CN}\right)\) was studied in the gas phase at \(215\ ^{\circ} \mathrm{C}\), and the following data were obtained:
Time (s) |

Calculate the average rate of reaction, in \(M/ \mathrm {s}\), for the time interval between each measurement. (b) Calculate the average rate of reaction over the entire time of the data from \(t=0\) to \(t=15,000\) s. (c) Which is greater, the average rate between \(t=2000\) and \(t=12,000\) s, or between \(t=8000\) and \(t=15,000\) s? (d) Graph \(\left[\mathrm{CH}_{3} \mathrm{NC}\right]\) versus time and determine the instantaneous rates in \(M/ \mathrm {s}\) at \(t=5000\) s and \(t=8000\) s.
