Hello everyone,
I have been trying to model surface reactions in fluent,my reacton is A(g)+B(s)==>AB , that AB is occupied solid's sites by gas and B(s) is unoccupied solid's sites ,otherwise total sites=1=occupied solid's sites+ unoccupied solid's sites

I have two problems:
1-My reaction should be defined as particle surface reaction or as wall surface reaction?and B , AB should be considered as solid species or site species?

2-How and where can I specify the mentioned relation about sites in the fluent?
I appreciate you taking the time to help me out with this.
