The isomerization of methylisonitrile to acetonitrile CH₃NC (g) → CH₃CN (g)
Is first order in CH₃NC. The rate constant for the reaction is 9.45 × 10^-5 s^-1 at 478 K. The half-life of the reaction when the initial [CH₃NC] is 0.030 M is ________ s.

Question

Quizplus · Accepted Answer

The half-life of a first-order reaction is given by the equation t_1/2 = ln(2)/k, where k is the rate constant. Substituting the given values into this equation, we get t_1/2 = ln(2)/(9.45 × 10^-5 s^-1) = 7.33 × 10³ s.
