The Isomerization of Methylisonitrile to Acetonitrile CH₃NC (G) → CH₃CN

The isomerization of methylisonitrile to acetonitrile CH₃NC (g) → CH₃CN (g)
Is first order in CH₃NC. The half life of the reaction is 1.60 × 10⁵ s at 444 K. The rate constant when the initial [CH₃NC] is 0.030 M is _ s^{- 1}.

A) 2.08 × 10^{- 4}
B) 4.80 × 10³
C) 7.10 × 10⁷
D) 2.31 × 10⁵
E) 4.33 × 10^{- 6}
