An experimental study of the gas-phase reactions of the NO3 radical with pent-1-ene, hex-1-ene and hept-1-ene

Abstract

Rate coefficients for the reactions between the NO₃ radical and pent-1-ene (k₁), hex-1-ene (k₂) and hept-1-ene (k₃) have been determined at T=296±1 K and P=759±7 Torr by a relative-rate method using the reaction between the NO₃ radical and but-1-ene (k₄) as the reference reaction. The values of the rate constants measured were k₁=(1.51±0.54)×10^-14 cm³ molecule^-1 s^-1, k₂=(1.85±0.66)×10^-14 cm³ molecule^-1 s^-1, k₃=(2.06±0.62)×10^-14 cm³ molecule^-1 s^-1 and the value of the reference rate constant was k₄=(1.35±0.41)×10^-14 cm³ molecule^-1 s^-1.
