Abstract

A kinetic model is presented that describes both homogeneous (k_q) and heterogeneous (γ) deactivation of O₂ (1Δ)(g) in a flow reactor experiment. The model is validated through measurements made on Pyrex surfaces where k_q and γ were found to be (1.6±0.4)×10^-18 and (3.1±0.2)×10^-5 cm³ s^-1 respectively. The model has been used to interpret data recorded for aged surfaces of the following metals: nickel γ= (3.2±0.2)×10^-4, copper γ= (2.9±0.2)×10^-4, 10 90 nickel-copper alloy γ= (2.8±0.2)×10-4, and inconel γ= (1.2±0.2)×10^-4.
