Methyl isonitrile first-order rearrangement

The change in concentration over time for the first-order rearrangement of gaseous methyl isonitrile at 199 °C is graphed in Figure 14.11. Because the concentration of this gas is directly proportional to its pressure during the reaction, we have chosen to plot pressure rather than concentration in this graph. The first half-life occurs at 13,600 s (3.78 h). At a time 13,600 s later, the methyl isonitrile pressure (and therefore. 

The rearrangement of methyl isonitrile (CH3NC) to acetonitrile (CH3CN) is a first-order reaction and has a rate constant of 5.11 X 10-5 s 1 at 472 K.
