The isomerization reaction,CH₃NC → CH₃CN,is first order and the rate constant is equal to 0.46 s^-1 at 600 K.What is the concentration of CH₃NC after 0.20 minutes if the initial concentration is 0.40 M?

Explanation:The integrated rate law for a first-order reaction is:ln[A]t=−kt+ln[A]0where [A]t is the concentration of the reactant at time t, k is the rate constant, and [A]0 is the initial concentration of the reactant.Substituting the given values into the integrated rate law, we get:ln[CH3NC]t=−(0.46s−1)(0.20min)(60smin)+ln(0.40M)ln[CH3NC]t=−5.52+−0.916[CH3NC]t=e−5.52+−0.916=1.6×10−3MTherefore, the concentration of CH3NC after 0.20 minutes is 1.6 × 10−3 M.
