At Elevated Temperatures, Methylisonitrile (CH₃NC) Isomerizes to Acetonitrile (CH₃CN)

At elevated temperatures, methylisonitrile (CH₃NC) isomerizes to acetonitrile (CH₃CN) :
CH₃NC (g) → CH₃CN (g)
The dependence of the rate constant on temperature is studied and the graph below is prepared from the results.
