Calculate the average rate of disappearance of isonitrile, in M/s, for the time interval between each measurement.

Solution

We are asked to calculate the average rate of disappearance of isonitrile, in M/s, for the time interval between each measurement.


We are given the following data:


Time (s)[CH3NC] (M)
00.0165
20000.0110
50000.00591
80000.00314
120000.00137
150000.00074


The isomerization of methyl isonitrile (CH3NC) to acetonitrile (CH3CN) has to the following reaction:

    CH3NC → CH3CN
