Expert Solution
Step 1

                            rate constant, k = 0.111 s-1

    Initial concentration of CH3NC = 1.557 M

Concentration after 18.9 seconds = ?

From the reaction and also from the rate constant units, we know that the reaction is first order reaction.

For first order reaction,

                                             [A] =[A]o e-kTln[A] = ln[A]o - kT

                                                  k =2.303t log [A]o[A]t
