Uptake of NO3 by KI solutions was measured at 273+/-1 K using a wetted-wall flow tube to determine the rate coefficient for the NO3(aq)+I- reaction to be k=(4.6+/-0.5)x10(9) M(-1) s(-1). It is suggested that the reaction of NO3 with halide ions proceeds by electron transfer. Use of high concentration of KI enabled determination of the gas-phase diffusion coefficients of NO3 in H2O vapor, He, N-2 and O-2 to be, respectively, D-NO3-H2O=120+/-15, D-NO3-He=345+/-25 D-NO3-N2=80+/-15 and D-NO3-O2=80+/-15 Torr cm(2) s(-1). These coefficients agree well with calculated values.
