Kinetic study of gas-phase Y(a 2D3/2) and La(a 2D3/2) with O2, N2O, CO2 and NO

The second-order rate constants of gas-phase Y(a 2D3/2) and La(a 2D3/2) with O2, N2O, CO2 and NO as a function of temperature are reported. In all cases, the reactions are relatively fast. For Y(a 2D3/2), the bimolecular rate constants (in cm3 s-1) are described in Arrhenius form by k(O2)=(2.2±0.1)×10-10 exp(-3.5±0.6 kJ mol-1/RT), k(N2O)=(1.9±0.2)×10-10 exp(-4.0±0.8 kJ mol-1/RT), k(CO2)=(1.0±0.1)×10-10 exp(-2.3±0.6 kJ mol-1/RT), where the uncertainties are ±2σ. The rate constants for Y reacting with NO are temperature insensitive with a value of 1.0×10-10 cm3 s-1. For La(a 2D3/2), the bimolecular rate constants for all the reactants are near the gas-kinetic collision rate.
