description: |-
A variation of the 2023 model of NH3 and H2 chemistry published by Alzueta and coworkers, with the original version denoted below as "baseline_mechanism". [1] In the modified version, "linear-Burke_mechanism", six complex-forming reactions have been modified according to the linear Burke rate implementation of the reduced-pressure linear mixture rule (LMR-R). These are: H2O (+M), HO2 (+M), H2O2 (+M), NH3 (+M), N2H4 (+M), and HNO (+M). Ab initio third-body efficiencies were obtained at discrete temperatures from Jasper [2] and then fitted to an Arrhenius parameterization to facilitate the temperature-dependence of these parameters. Further description of the methodology used to adapt this mechanism is available in Singal et al. [3]
This mechanism includes three complex-forming reactions, shown with and without
the linear-Burke implementation. All parameters are idealized and are only
intended for demonstration. Do not use this mechanism for any other scientific
purposes. The thermodynamic and transport data were taken directly from Alzueta et
al. [1], and the reactions were adapted from the linear-Burke model of Singal et al.
[2].
