Heterogeneous reaction

Gases can react on an aerosol surface. The reaction rate can be determined using the following parameterization for the reaction constant.

 $k=\left ( \frac{r}{D_{g}}+\frac{4}{vy} \right )^{-1}A$ The reaction rate k is related to  r Radius of particle Dg Gas-phase diffusion coefficient v Mean molecular speed γ Reaction probability A  Aerosol surface Note that aerosol surface is not equivalent to effective surface (BET), due to presence of pores.

Execution

 These equations are purely deterministic and can easily be solved using a pocket calculator or spreadsheet software.
