Temperature Dependence of Reactions of the Nitrate Radical with Alkanes
Rate constants have been determined as a function of temperature for the reaction of NO3 with n-butane, i-butane (2-methylpropane), i-pentane (2-methylbutane) (298-523K) and ethane (453-553K). Arrhenius expressions for the reaction of NO3 at primary, secondary and tertiary hydrogen atom sites have been derived and used to predict the rate of reaction between NO3 and i-pentane. The observed decays of NO3 could be reproduced by kinetic models using a reasonable mechanism.
