LHM & ERM NO oxidation and the adsorption configurations of NO2* bidentate

Inspired by this paper, NO oxidation can proceed by

1. NO* + O* <=> NO2* Langmuir–Hinshelwood Mechanism(LHM)
2. NOgas + O* <=> NO2* Eley–Rideal Mechanism (ERM)

This paper also proposed a more stable O,O' bidentate structure of NO2 adsorbate on the bimetallic surface that

We have thermo data for both structures, it can be found by searching these two adjcencyLists

1 O u0 p2 c0 {3,S} {5,S}
2 O u1 p2 c0 {3,S}
3 N u0 p1 c0 {1,S} {2,S} {4,S}
4 X u0 p0 c0 {3,S}
5 X u0 p0 c0 {1,S}

and

multiplicity 2
1 O u0 p2 c0 {3,S} {5,S}
2 O u0 p2 c0 {3,S} {4,S}
3 N u1 p1 c0 {1,S} {2,S}
4 X u0 p0 c0 {2,S}
5 X u0 p0 c0 {1,S}

Presently, we don’t have a family or library to deal with these mechanisms (both LHM and ERM). One similar template is from the Surface_Dissociation family

 *1--*2                 *1     *2                        *O--*N=O               *O     *N=O
  |            ---->    ||      |        which is         |            ---->    ||      | 
~*3~ + ~*4~~           ~*3~ + ~*4~~                     ~*3~ + ~*4~~           ~*3~ + ~*4~~

Another similar one is in the Surface_Bidentate_Dissociation family

 *1--*2              *1   +   *2                      *O--*N-O              *O   +   *N-O      
  |   |     ---->    ||       ||          and          |   |     ---->      ||       ||          
~*3~~*4~~           ~*3~~ +  ~*4~~                   ~*3~~*4~~             ~*3~~ +  ~*4~~             

while X=N-O is not a representative species in RMG and we don't have thermo data of this adsorbate

Maybe we can consider a template or library like this?

 *1       *2=*5          *1--*2-*5              *O       *N=*O          *O--*N-*O
 ||        |    ---->     |   |         and     ||        |    ---->     |   |
~*3~  +  ~*4~~          ~*3~~*4~~              ~*3~  +  ~*4~~          ~*3~~*4~~

One more thing to discuss is the value of sticking coefficient for reaction NO2gas + * <=> NO2* reported in table I, which is:
A= ((2.24E2 /bar)/ s)(2.483E-9 mol/cm2)sqrt(2pi46 g/mol * molar gas constant * 298 kelvin)= 1.4884E-6
Comparing the value reported in RMG is A= 0.2, which is very different.

I am not confident with this value and not sure if we could include this in the training reactions.

Start by reviewing the Surface_Dissociation and Surface_Bidentate_Dissociation families, then inspect the two supplied adjacencyLists and their thermo data. The work is complete only when the intended LHM and ERM representations, bidentate adsorption configurations, and the proposed NO2 sticking coefficient or training-reaction treatment are explicitly decided and supported.
