A liquid phase dimerization reaction occurs according to the following equation: 2A B. Both the reactant and product are dissolved in a solvent that is non-reactive (inert), and the reaction occurs at a solid catalyst surface. The concentration of A in the bulk liquid is CA, and the concentration of A at the surface is Caz. The reactants diffuse from the bulk liquid to the catalyst surface across a film of thickness 8. a) Draw and label a sketch of the system, including all concentrations and dimensions. Clearly show the directions of the fluxes of A, B, and C (N, N., and N.). (5 points) b) Starting with the following convection diffusion equation, and assuming that the system is diffusion controlled, derive an equation for the flux of A (NA). Show all work and state all assumptions. (20 points) NA=-DAC dCA CA (NA+Ng+Nc) dz Cave +
