Show all intermediate steps from the geometry to the final particular solution of your required profile.

2. Given that there is transport of 4 moles of A and 2 moles of B towards a permeable membrane from the bulk. The film between the membrane and the bulk is 2 microns thick. The concentration of A at the bulk is CA,bulk=1M and at the interface is CA,i=0.5M. Under steady state conditions, derive the concentration profile (particular solution) of A and B for the following two conditions: (a) Neglecting convective fluxes in the film (b) Not neglecting convective fluxes in the film
