Activated gaseous flux

Level II and III indicators may include more comprehensive measurements such as enzyme activity, denitrification, microbial and algal diversity, microbial biomass, primary production, and acid volatile sulfide and gaseous flux measurements to name a few. 

At high temperatures, activated gaseous diffusion or translational diffusion becomes the dominating transport mechanism. Then the permeation flux can be expressed by... 

When activated gaseous diffusion occurs, the flux is described by the next... 

The flux of flie adsorbed species to die catalyst from flie gaseous phase affects die catalytic activity because die fractional coverage by die reactants on die surface of die catalyst, which is determined by die heat of adsorption, also determines die amount of uncovered surface and hence die reactive area of die catalyst. Strong adsorption of a reactant usually leads to high coverage, accompanied by a low mobility of die adsorbed species on die surface, which...
