2. The following table gives data on the isomerization of CH3NC to CH3CN, in the gas phase: CH3NC(g) → CH3CN (g) Use a graphical method to show that the reaction is first order. Determine the rate constant and the half-life. Time (s) 0 1000 4000 8000 11000 14000 Pressure of CH3NC (bar) 0.673 0.547 0.293 0.128 0.0684 0.0366
